; File: ShutDownMgr.a
;
; Contains: This file contains the core routines pertaining to the ShutDown trap
; for both the ROM and the System.
;
; ShutDown takes a command parameter and either:
;
; sdInit: 0) initialize the ShutDown queue
; sdPowerOff: 1) turn the power off (or give a dialog on machines without soft power-down)
; sdRestart: 2) restart the machine
; sdInstall: 3) install a ShutDown task in the list
; sdRemove: 4) remove a ShutDown task
; sdUserChoice: 5) notify the user that the machine is going to power off, then turn power off
; sdSoftOff: 6) notify the user that the machine can be ShutDown, or return to Finder

; Change History (most recent first):
;
; <SM33> 11/6/93 SAM Roll <MC8> from mc900ftjesus.
; <MC8> 11/6/93 SAM Now handle the restart from the "..safe to switch off..." case
; correctly (ie restore the nanok warmstart).
; <SM32> 11/6/93 SAM Roll <MC7> from mc900ftjesus.
; <MC7> 11/6/93 SAM Changed ClearWarmStart to check for a V0 style emulator and if
; present to clear the emu warmstart flag.
; <SM31> 10/29/93 CCH Modified KillEDisk to deal with EDisks that don't use checksums.
; <MC5> 10/11/93 CCH Modified KillEDisk to use new HwPriv parms on PowerPC.
; <MC4> 9/27/93 SAM Added ClearWarmstart too.
; <MC3> 9/27/93 SAM Added exports of DoRAMDiskAlert, KillEDisk, FindEDisk,
; ShutRestart, and ShutPower for vectorization.
; <MC2> 9/25/93 SAM Completely cleaned up this file. Removed tons of shit, bogus
; and sloppy code. Looking more and more like it was in Terror...
; <SM28> 8/12/93 BG Converted references to gestaltCyclone40 to gestaltQuadra840AV.
; <SM27> 7/20/93 SAM Removed the Scruffy code from ShutRestart. (we will never be a
; Mac II).
; <SM26> 7/13/93 RB For the third time, removed checks for 67C ROM.
; <SM25> 6/14/93 kc Roll in Ludwig.
; <LW3> 5/27/93 KW Added code in the Shutdown Continue Proc from the
; ShutDownMgrPatches.a from the gibbly to remove the Chassis Sw
; TimeMgr Task if you are running on a Cyclone CPU. The Chassis Ss
; TimeMgr Task is piggybacked onto the emKeyTmTaskPtr
; <LW2> 5/14/93 KW After calling "DoRAMDiskAlert", if user hit cancel remove the
; tickletimer and send cuda and EnDisPDM command with PDMContinue.
; Fixes some radar bug
; <SM24> 4/8/93 SAM Added some Supports24bit conds around swapmmu code in
; ClearWarmStart and KillEDisk.
; <SM23> 3/9/93 jmp Cleaned up the ShutDown/Restart blank-the-screen code so that it
; now works more consistently across all CPUs (i.e., due to the
; fact that various CPUs these days don't tie reset to I/O, the
; desktop could sometimes persist thru bootbeep).
; <SM22> 01-18-93 jmp Added a TimeMgr-based timeout task that forces the wait-eject
; code to terminate (if it isnÕt already done) after 2 seconds.
; This prevents things like stuck disks, etcÉ, from hanging the
; restart/shutdown sequence.
; <SM21> 12-17-92 jmp Removed the Wait500ms routine in favor of Òwait for floppy
; ejectÓ described in <SM20>.
; <SM20> 12-16-92 jmp Added some code that waits until the drive queue has noticed
; that all floppies have been ejected (in DoUnmount) before
; shutting down or restarting.
; <SM19> 12/9/92 RB Remove (AGAIN) the check for Terror ROMs regarding EDisk. This
; ain't Terror, Also save and restore A5 in BlankScreen so that
; the cursor is not trashed on Macs that don't support soft
; shutdown.
; <SM18> 11/20/92 FU Removed another tickle cuda call.
; <SM17> 11/20/92 RB Removed the call to TickleCuda.
; <SM16> 11/20/92 GS (bg) Updated ShutPower to include the chks for Sonic to issue a
; reset to the Sonic Chip before executing the Shutdown. Removed
; the EnablePDMsgs from ShutInit. Now found in Boot3.a. Added
; the CloseLCDVideo, DockInitSCC routines for the portables.
; <SM15> 11/3/92 SWC Changed ShutdownEqu.a->Shutdown.a and SlotEqu.a->Slots.a.
; <SM14> 10/8/92 GS Added a 500ms delay before pulling the power plug in the
; ShutPower routine to help with the async call by New Age to
; eject the floppy.
; <SM13> 9/28/92 RB Fix the Soft Power Shutdown on the Quadra 900 and 950. ¥¥¥ WHEN
; UPDATING FROM REALITY OR HORROR, DO NOT MESS WITH SHUTINIT, make
; sure that it still calls EnablePDMsgs, AND that EnablePDMsgs has
; a ble, not bne !!!!!
; <SM12> 9/3/92 PN Nuke the check for IIci because this is SuperMario.
; <SM11> 8/19/92 CSS Update from Reality:
; <52> 8/18/92 DTY Change the name of BootGlobs to StartGlobals to avoid confusion
; with BootGlobals, which is used by the boot code in Boot[1-3].a.
; <SM10> 7/28/92 MR Restart crashes under VM because a switch
; to supervisor mode is done only if ROM is IIci. Now checks for
; SuperMario
; <SM9> 7/7/92 CSS Update from Reality:
; <51> 6/2/92 JSM #1031451 <csd>: Like we do on the PowerBook 140 and 170, close
; the video driver at shutdown or restart for the PowerBook 145.
; <50> 4/9/92 JSM #1026795,<DTY>: Set CLUT to 50% gray on restart for the LC II as
; well as the LC.
; <SM8> 7/1/92 RB Do the EDisk check at Shutdown without checking the ROM version
; of Terror, since SuperMArio also has Edisk. Do not call Cuda on
; machines without it.
; <SM7> 6/26/92 GS ReIncluded ROMBind, InstallProc, and PatchProc Linked Patch
; Macro calls to support CubeE builds.
; <SM6> 6/23/92 GS Having a problem with the latest set of check-ins. The Header
; format could not be found. Cleaning up header...
; <SM5> 6/23/92 GS Was a Bad Dog!!!! Re Including the LinkedPatchMacros.a for
; support of Non-SuperMario ROM based machines.
; H/W specific chks in place for Egret chip with Cuda FW.
; Rolled in changes for the Soft Power off support with code from
; Cyclone version of Regatta. This includes chks in the sdSoftOff
; code to chk for Cuda FW in the Egret chip. Removed Linked patch
; macro support.
; <SM3> 5/16/92 kc Roll in Horror Changes. Include PowerPrivEqu instead of
; ROMPrivateEqu.
; <SM2> 4/1/92 JSM Roll-in changes from Reality:
; <49> 4/1/92 JSM #1025166,<DTY>: Roll-in code formerly in the file
; ShutDownRAMDiskPatchINIT.a that puts up a warning dialog if a
; user tries to shutdown with a RAM disk, and make it work for ROM
; builds, too.
; <48> 2/11/92 JSM Moved this file to ShutDownMgr folder, keeping all the old
; revisions; cleanup header.
; <47> 12/4/91 csd #1016450: Added support for Scruffy. If Scruffy is running, we
; turn off the MMU before jumping to the ROM code which does a
; RESET. Otherwise, the RAM-based MMU tables get lost when the
; RESET causes the ROM to overlay RAM.
; <46> 12/2/91 SAM Using official boxflag equates now.
; <45> 10/29/91 SAM Fix comment header.
; <44> 10/29/91 SAM Special case the Macintosh Portable in the Restart code to not
; execute the RESET instruction.
; <43> 10/28/91 SAM/KSM Rolled in Regatta changes. Fixed up the Restart sequence.
; Mike saves my butt. (JMP) Changed the branch case after the
; call to FindEDisk and explicitly set D0 if an EDisk was found.
; Added code to "_Shutdown" poweroff to look for an EDisk and if
; found to clear its checksum data - effectively invalidating the
; disk (no matter how much the RAM persists after a shutdown!)
; Changed register usage of last change from A1 to A0. It was causing
; non Jaws machines to hang at restart
; (HJR) Added new restart sequence for Tim because of some hardware
; limitations. (BG) Universalized the code that decides whether to
; enable PowerDownMsgs.
; (jmp) Added an include for 'InternalOnlyEqu.a' for BoxFlags.
; Modified the DoDrivers routine to not ÒkissÓ the TIM, TIM-LC,
; Spike, and Eclipse video drivers goodbye. Modified the
; ShutRestart & ShutPower routines to turnoff TIM and TIM-LC video
; after all restart procs have been run.
; All $67C machines that are running VM will get switched into
; supervisor mode before jumping to the ROM restart vector. Non
; $67C's never switch to supervisor mode. (bg) Enable Egret
; PowerDown messages on Eclipse.
; <42> 7/10/91 dba end of the forPost70 conditional; we are past 7.0 for good
; <41> 6/12/91 LN added #include 'ROMPrivateEqu.a'
; <40> 6/12/91 LN removed #include 'HardwareEqu.a'
; <39> 6/11/91 gbm dba, dty: change Gestalt call for post-7.0 to check
; hasSoftPowerOff instead of SE/30 machine type; also use new
; Òneeds RESETÓ selector; and nuke Regatta conditionals
; <38> 4/2/91 dba use the real _EnterSupervisorMode from Traps.a, instead of
; defining a local constant here
; <37> 4/2/91 SAM Changed the Restart code to put the machine back in Supervisor
; mode (if VM is on) before restarting (in the Regatta build).
; <36> 3/13/91 bbm &dty; I almost got it right last time. I need to make sure that
; the shutdown tasks get executed on machines that have no soft
; poweroff.
; <35> 3/11/91 bbm &CCH; <#31191bbm>; Userchoice automatically did the poweroff
; routines even though we may be doing a restart. This meant we
; did a cold start even though we wanted a warm start.
; <34> 3/4/91 dba dty: get rid of SysVers conditionals
; <33> 1/15/91 stb & dba; fix ROM build by changing JSRROM to JSRROM.FAR
; <32> 1/14/91 stb & PKE; Fix lack-of-port bug in BlankScreen
; <31> 1/8/91 SAM Changed all occurrences of gestaltXO to GestaltMacClassic
; <30> 1/8/91 gbm (dba) use peaResident to avoid losing modules
; <29> 9/25/90 SAM Changed boxElsie/boxErickson to boxMacLC/boxMacIIsi.
; <28> 9/13/90 BG Removed <24>. 040s are behaving more reliably now.
; <27> 8/31/90 CV Moved the code to gray the Elsie screen on shutdown to occur
; after shutdown tasks are executed.
; <26> 8/24/90 SAM Added StripAddress to InitShutDown to lose the HiBits in the
; proc ptr so the CPU doesnt puke on an RTS in 32 bit mode.
; <25> 8/23/90 GMR NEEDED FOR SIXPACK!! Fixed task which clears warmstart to make a
; runtime check on HwCfgFlags before calling SwapMMUMode.
; <24> 7/16/90 BG Added EclipseNOPs for flakey 040s.
; <23> 6/25/90 CCH Added EXPORT of ShutDownDisp.
; <22> 6/22/90 DTY Fixed includes so ROM builds donÕt break.
; <21> 6/21/90 DTY Moved ShutDownMgrINIT.a InstallProc to end of this file. Moved
; _SDInit code into InstallProc. System versions of ShutDown
; Manager will not have _SDInit as a selector. _SDInit selector
; still available in ROM builds. Check gestaltMisc for
; gestaltSquareMenus to determine background colour in BlankScreen
; instead of looking at machine type.
; <20> 6/21/90 DTY Shutdown Manager now loaded as lpch on all systems. Removed all
; references to asINIT. Changed entry point of _Shutdown to
; ShutDownDispatch. _SDInit code comes after dispatch routine,
; and now called from ShutDownMgrINIT.a.
; <19> 6/20/90 DTY Made Shutdown Manager a linked patch under 7.0
; <18> 6/18/90 DDG NEEDED FOR SIXPACK: Fixed use of RESET instruction, so that we
; RESET on an XO.
; <17> 6/18/90 DDG NEEDED FOR SIXPACK: fixed the graying of the elsie screen (we
; need to use ioRefNum instead of ioVRefNum).
; <16> 6/12/90 DAF Added CLUT-based screen graying on restart for Elsie only.
; <15> 6/11/90 DTY Pass Shutdown constants from ShutDownEqu.a instead of sdBit
; constants to RemoveOtherType to get proper bit alignment for the
; compare.
; <14> 6/11/90 DDG NEEDED FOR SIXPACK: Put back some obsolete code that checks for
; the presence of switcher and calls _ExitToShell instead of
; shutting down. This fixes a bug in OnCue.
; <13> 6/8/90 DTY Added RemoveOtherType routine to remove sdOnRestart procedures
; when calling ShutDwnPower, and to remove sdOnPowerOff procedures
; when calling ShutDwnRestart, so that CallRoutines can
; differentiate between the two, and provide more specific times
; to call shutdown routines.
; <12> 5/29/90 DDG NEEDED FOR SIXPACK: Changed all the sixpack conditionals from
; six-point-oh-seven to six-point-oh-six.
; <11> 5/16/90 DDG NEEDED FOR SIXPACK: The ClearWarmStart routine now checks for the
; machine being a Mac Plus, and if that is the case, then
; WarmStart is NOT cleared (it doesn't exist on the MacPlus)
; <10> 5/2/90 CV Adding include of 'GestaltPrivateEqu.a'.
; <9> 3/22/90 GA Removing the code which stops Egret ADB autopoll and
; Egret one second interrupts. These functions are now
; done by diagnostics calling a routine in EgretMgr.a
; <9> 3/22/90 GA Removing the code which stops Egret ADB autopoll and Egret one
; second interrupts. These functions are now done by diagnostics
; calling a routine in EgretMgr.a
; <8> 2/28/90 GA Changed the System Restart code supporting Egret to conform with
; the new Egret Manager Parameter block Model.
; <7> 2/15/90 GA Changed the Conditional if hasEgret to If ForRom AND HasEgret to
; fix a broken BigBang Build.
; <6> 2/14/90 GA Added support to the Restart code to issue a stop autopoll and
; stop 1 sec. irq to Egret before restarting the system.
; <5> 1/12/90 SES NEEDED FOR 6.0.5: Added shut down task to clear warm start flag
; on a power off. This means that the machine will do a cold start
; if the user selects 'Shut Down', but will still do a warm start
; if the user selects 'Restart'.
; <4> 1/11/90 CCH Added include of ÒHardwarePrivateEqu.aÓ.
; <3> 1/3/90 CCH Changed Gestalt equate filename back to GestaltEqu.a.
; <2> 1/2/90 CCH Changed the name of the Gestalt equate file.
; <3.0> 11/2/89 dba exported ShutInit
; <2.9> 10/31/89 dba changed to load as a patch instead of an INIT
; <¥2.9> 10/31/89 dba forced submission (Reality was full)
; <2.8> 10/11/89 dba added sdUserChoice selector; added comments; made some more
; subroutines; got rid of some code to handle Switcher and 128K
; Macs; got rid of equates which are already in ShutDownEqu.a;
; changed rules for white border, soft power-off, and RESET (these
; will use new Gestalt selectors before 7.0 ships)
; <2.7> 7/12/89 GGD NEEDED FOR AURORA, once again, changed which machines do a RESET
; inst in the Restart code. Added comments explaining why some
; machines need it, and why some others must not use it.
; <2.6> 6/26/89 PKE NEEDED FOR 6.0.4 (and 7.0): Fixed definition of DHTrapNumber.
; <2.5> 6/20/89 CCH Put RESET back in for all but HcMac.
; <2.4> 6/20/89 CCH Modified to assemble for System file.
; <2.3> 6/15/89 CSL Took out the temporary quick and dirty fix in shut down with
; parity RAM.
; <2.2> 5/30/89 CSL Temporary quick and dirty fix for shut down with parity RAM,
; zero out WarmStart during power off to ensure a real cold boot
; next time.
; <2.1> 5/23/89 DAF Hid cursor on powerdown for Aurora
; <2.0> 5/10/89 CCH Removed RESET instruction, since either weÕre powering down or
; jumping to ROM, which will do a RESET anyway.
; <1.9> 4/27/89 CCH DoesnÕt execute a RESET on restart if running out of RAM.
; <1.8> 3/6/89 GGD Changed ReStart again, jump to restart routine at ROMBase+$0A,
; instead of fetching the reset PC from the ROM, to allow for the
; case where the reset PC may not point into read ROM space (may
; use zero based space). Added support for RAM based ROM onMacPP,
; to not execute a reset instruction on restart. Included
; HardwareEqu.a for rom header equate.
; <1.7> 2/21/89 rwh fix restart - canÕt assume RAM present after a reset.
; <1.6> 2/8/89 MSH DonÕt use the RESET intruction on the portable
; <1.5> 11/21/88 CCH Changed ForRam equates to ForRom.
; <1.4> 11/18/88 DHD Cased out the portable during shutdown we always call _PowerOff
; <1.3> 11/16/88 CCH Took out include of ÒnTraps.aÓ
; <1.2> 11/16/88 DAF Updated restart for Mac II machines
; <1.1> 11/10/88 CCH Fixed Header.
; <1.0> 11/9/88 CCH Adding to EASE.
; <1.6> 10/11/88 DHD Updated screen clearing code to work on any CPU
; <1.5> 10/11/88 DHD removed code specific to the portable Mac.
; <¥1.4> 9/23/88 CCH Got rid of inc.sum.d and empty nFiles
; <1.3> 9/9/88 MSH Removed hardware equate use for clearing screen before sleep.
; Use lomem values instead.
; <1.2> 9/6/88 MSH Added screen clear and delay for disk eject before sleep.
; <1.1> 7/21/88 MSH Add Sleep and reset to HcMac shutdown.
; <1.0> 2/11/88 BBM Adding file for the first time into EASEÉ
; <DHD> 9/15/87 DHD Donn Hilsinger Denman that is - Changed the UnMountVol to the HFS
; flavor or UnMount. This really does an UnMountVol regardless of
; whether or not there are open files. Since the disk will be shut
; down, it seems like the right thing...
; <EKH> 8/25/87 EKH Ed Heyl that is - Added '_ShutDown' equate so that it would build
; under MPW 1.0 - remember Don that is what everybody else uses. I
; copied the equate from MPW 2.0s AIncludes:Traps.a.
; <DLD> 4/6/87 DLD Now clear the resume proc before putting up the shutdown alert, so
; the resume button wonÕt show.
; <DLD> 11/19/86 DLD Fixed a bug in ShutInstall. Was pushing the return address twice.
; Removed push just before RTS.
; <DLD> 9/5/86 DLD changes ForROM
; <DLD> 8/22/86 DLD New today.

; Some history for all you young'ns:
;
; Some things to be aware of about the RESET instruction on various Macintosh Products <2.7>
;
; 1) This code is in ROM on Aurora, Esprit, F19, and all new CPUs. It is in RAM, from
; the System Disk on the Mac Plus, SE, II, IIx, IIcx, SE30.
;
; 2) StartInit contains a RESET instruction in ROM on the 68020/030 CPU ROMs.
;
; 3) On the Mac Plus and Mac SE, a RESET will cause the 68000 to get a Reset, and it
; will switch into overlay mode, and Re-Boot through the reset vector.
;
; 4) When running a ROM image out of RAM, we do not want to do a RESET, because it will
; cause a switch into overlay mode, and the RAM base code cannot be fetched.
;
; 5) On 68030 based machines, if the translation tables are in RAM (AURORA/F19, VM or Romulator),
; you should not do a RESET when the MMU is enabled, even if you are executing in ROM.
; If there is a miss in the ATC, it will attempt to fetch descriptors from RAM, but overlay
; is now enabled, and data from ROM will be used instead, causing lots of problems.
;
; 6) Esprit has some problem when RESET is executed, and RESET should NEVER be used.
;
; 7) This all means that RESET is only needed on a MacPlus and MacSE.
; It might not be a problem on machines based on the MacII/IIx ROMs,
; since they have the MMU tables in ROM, but it is not reccommended.
; All other situations should not do a RESET in Shutdown.
