; File: StartBoot.a
;
; Contains: This part of the Start Manager locates the Startup Device, loads its driver
; (if it hasn't already been loaded by InitIO), and asks the driver to get the boot blocks.
; It uses information in the boot blocks to initialize system variables,
; decide whether to load a debugger, and launch a Startup Application.

; Change History (most recent first):
;
; <SM58> 1/28/94 chp Roll back <SM56> which is no longer required.
; <SM57> 12/6/93 DCB ShutInit was being called twice. The ShutDown queue is already
; setup in StartInit.a. The second call to it in InitSys7Toolbox
; blows away all ShutDown tasks that have been installed since the
; system booted. Since this is undesirable I am getting rid of the
; second ShutInit.
; <SM56> 11/10/93 chp Disable LateLoad on TNT (for now).
; <SM55> 11/7/93 SAM Roll in <MC5> from mc900ftjesus.
; <MC5> 11/6/93 SAM Removed <MC3>. Eric beat me to it. VM pokes the level 4 irq
; handler into the supervisior vector table itself.
; <SM54> 10/15/93 SAM Roll in <MC4> from mc900ftjesus.
; <MC4> 10/15/93 SAM For PDM. The DMA irq hander is now installed in the supervisor
; vector table when VM is on.
; <SM53> 9/29/93 SAM From mc900ftjesus.
; <MC3> 9/27/93 SAM Cosmetic changes.
; <MC2> 9/26/93 pdw Removed extra OptimizePACKs.
; <SM52> 9/2/93 IH Add Display Manager Install to boot process.
; <SM51> 8/5/93 JDR integrate Component Mgr from Reality
; <SM50> 8/4/93 JDR Integrate sound manager 3.0 project.
; <SM49> 7/20/93 SAM Cleaned up this file a bit. Rewrote what used to be
; "installmgr." Removed a patch file in the process. This change
; fixes the "the top 1/3 of my Cyclone system heap is not heal
; down with VM on" and quite a host of others... Moved all that
; disabled password junk to the end of the file.
; <SM48> 5/30/93 SAM Commented out Robert's password thing and the syserr F-Line
; patch that would destroy the pc of the offending instruction.
; Moved the ROM_EM stuff to Tidbits.
; <SM47> 4/9/93 SAM Commented out the calls to init Bass (they've been moved to
; StartInit. (INSTALLBASSCOMMON and FORCEINITFONTSCALL)
; <SM46> 3/25/93 RB Added Robert Polic's password-on-boot code from Ludwig.
; <SM45> 2/13/93 PW Reenabled LateLoad for PDM.
; <SM44> 2/6/93 RC Comment out LateLoad for PDM since the last change caused PDM to
; Hang on Boot
; <SM43> 2/5/93 PN Adding scsiLateLoad into the end of InstallMgr
; <SM42> 1/12/93 PN Fix a bug where in InitFonts it used emSplineKey which is not
; yet initialized. So the call InstallBassCommon has to precede
; Initfonts. InitFonts is taken out of this file because it is
; called in the boot block before Welcome to Macintosh.
; <SM41> 12/16/92 SWC Moved InitEvents->OSEventMgr.a and CenterRect->StartBoot.a.
; Removed dead code.
; <SM40> 12/3/92 PN Add AfterBootSetApplBase to the InstallMgr to patch out
; SetApplBase trap at Gibbly time
; <SM39> 11/24/92 RB Use the feature hasROM_EM so it can be easily taken out, because
; Steve Glass doesn't want the extra feature in his ROMs.
; <SM38> 11/23/92 RB Moved an LC930 conditional.
; <SM37> 11/20/92 rab Changed BootMe to call ReBoot if execution of the Boot Blocks
; fail. This allows BootMask to be updated and proper booting to
; continue if a device with Boot Blocks but no System is
; encountered.
; <SM36> 11/18/92 RB Add a call to the Disk Cache installation routine from the
; InitManagers call.
; <SM35> 11/5/92 RB Add a call to check the state of the extensions at the end of
; InstallMgr.
; <SM34> 11/3/92 rab Horror ROM sync-up. Rolled CloseNetBootPatch from Horror
; StartInit.a into Reboot.
; <SM33> 10/30/92 HY Add "Ginty" support to boot process.
; <SM32> 10/28/92 PN Remove LoadProcessMgrSegmentLowerInSysHeap since it's been done
; in BootCode3.a and call the QDSecondaryInit.
; <SM31> 10/26/92 RB Exclude any unused code from the LC930 build (1 Meg ROM). System
; 7 never returns control to the ROM after executing the Boot
; blocks, and we are System 7 based.
; <SM30> 9/15/92 RB The Boot code in Cube-e has a list of ROMs it knows about
; (Boot1.a), as it finds a ROM it sets up a parameter block
; pointer in d7, but if it does not find the ROM id d7 is never
; setup and later used as am parameter block, therefore the last
; value in d7 gets used as param block pointer and memory
; somewhere is trashed. So just in case set d7 to our boot time
; param block before we execute the boot blocks.
; <SM29> 9/10/92 AEK Removed call to InstallTimeMgr (not needed if new TM in ROM)
; NOTE: TimeMgrPatch.a should now be removed from ROM builds
; <SM28> 8/20/92 PN Call InstallSndPrimitives at boot time
; <SM27> 7/13/92 CCH Don't call the _VM trap unless it's implemented.
; <SM26> 6/30/92 PN Adding init routines to set up CommToolbox in SuperMario
; <SM25> 6/30/92 JSM InstallSpeedScrollGlob is now InitScrollSpeedGlobals.
; <SM24> 6/26/92 FM Remove call to resource manager install proc since all it does
; is unimplement the AddReference and RmvReference traps. We can
; do that in DispTable.a.o
; <SM23> 6/25/92 PN Move InitFasterInvals into StartInit.a
; <SM22> 6/12/92 PN Roll in patchIIciROM.a. Check for PowerBook140 and set the
; boxflag is moved to StartInit.a.
; <SM21> 6/11/92 PN Roll in patchIIciROM.a installing vector for the "FPU not
; installed" dialog box if we don't have FPU. Install optimized
; package4 and package5. Check and put in the correct boxflag for
; PowerBook140.
; <SM20> 6/10/92 JSM InstallDilogGlobals is now InitDialogMgrGlobals.
; <SM19> 5/16/92 kc Remove call to ADBMouseInit. This patch is already rolled
; inline.
; <SM18> 5/6/92 TN Initialize the Notification Manager here instead of from an
; InstallProc.
; <SM17> 4/27/92 PN Put VMSecondaryInitialization and add a routine to init global
; memory for scrollspeedfix
; <SM16> 4/22/92 PN Roll in hasSoftPowerOff and GestaltColorQuickDrawFeatures into
; GestaltFunctions and remove these routines from InstallMgr. Also
; FontMgr Gestalt moves to GestaltFunction.a
; <SM15> 4/16/92 PN Adding TrueType initialized call (SplineCall) to the start code
; <SM14> 4/14/92 kc Add call to BTreeInstall.
; <SM13> 4/8/92 RLM add call to init DialogMgrGlobals
; <SM12> 3/31/92 PN Adding Init routines for ComponentMgr and TextServiceMgr
; <SM11> 3/24/92 PN Remove SoundMgr initialization stuff and adding
; ProcessMgrSegmentTweak
; <SM10> 3/11/92 PN Adding MiscPatches into the InstallMgr
; <SM9> 3/10/92 PN Adding call to initialize soundmgr
; <SM8> 3/6/92 PN Taking out HFSInit and BTReeinstall
; <SM7> 3/4/92 PN Putting InstallMgr back in
; <SM6> 3/3/92 kc Roll out all SuperMario changes and move them into StartInit.a.
; <SM5> 2/19/92 RLM move installs
; <SM4> 2/13/92 PN Add InstallMgr.
; <SM3> 2/13/92 RLM Add NotificationMgrPatch roll-ins
; <SM2> 2/12/92 RLM InstallProc roll-in from SCSILinkPatch.a.

; be used instead of the disk version, unless there is a ROM
; override.
; <1.6> 5/24/89 GGD Converted to feature based conditionals.
; <1.5> 4/10/89 gmr Changed ReBoot to not call eject if the boot drive was not
; ejectable (DIP=08), and after calling eject, if the drive was
; not ejectable (DIP=$48), clear the BootMask bit for the drive
; (e.g. on RAM disks) so we won't keep trying to boot off them.

; <C692> 1/25/87 GWN Changed sType to 8-bytes.
; <C682> 1/24/87 WRL Allow a PICT 0 resource in the StartupScreen file. This allows

; for color startup screens.
; <C641> 1/15/87 GWN Get seOSType and seReserved from PRAM.
; <C592> 1/5/87 GWN Added code to erase happy Mac (Need to add a test to see if

; setting, if no flag register is present, is yes).
; <C452> 11/21/86 GWN Added code to Open all slot drivers.
; <A403> 11/11/86 WRL Fix to handle old HD20 drivers which pretended hard disks were
; ejectable. This caused them to be retried forever if the System
; file isn't present.
; <A286> 10/28/86 WRL Put in a check to make sure proposed system heap size is
; reasonable.
; <A271> 10/27/86 BB Changed switcher table set up for WDCBs and PMSP to use use long
; addresses.
; <C277> 10/27/86 SMH Changed the mouse tracking init code in Startinit.a,
; startboot.a, CCrsrCore.a and CrsrCore.a for Time Averageing

; and kbd.a
; <C206> 10/9/86 bbm Modified to mpw aincludes.
; <C152> 9/13/86 WRL Major cleanup after code review. Modified boot block version
; paradigm to allow for relative system heap sizes. Removed
; InitDrvr subroutine - it is now called from kbd.a as
; InitADBDrvr. We now unmount the boot volume if we discover that
; it has no system file. Replaced search for boot device with code
; in StartSearch.
; <C108> 8/6/86 WRL Aladdin wants a 96k system heap as well. Removed load of "ADBS"
; resources for NuMac - new ADB not in yet.
; <C104> 8/4/86 WRL CSL Added temporary fix for loading "ADBS" resources
; <C56> 7/1/86 WRL [NuMac] Increased system heap to 96k. Removed old check for 128k
; machine.
; <C46> 6/16/86 WRL Changed label NoDir to @NoDir so as not to conflict with Slot
; equates. Changed JSR InitCache to BigJsr.
; 1/20/86 ELR Added ROM75Fix bug patches: (1) set up BootDrive before
; prefixing to StartUp App folder; (2) don't skip OpenWD if folder
; is the root - the File System should return a VRefNum anyways,
; and the SetVol is needed to find a file in the root if current
; prefix is to a folder.

; CheckForROMDisk
;
; The following code supports the "Ginty" ROM disk architecture (System Disk in ROM).
; The idea is to pass control to the ROM disk so it can decide whether or not
; to boot from the ROM disk. If there is no ROM disk present or this particular machine
; does not support it then we continue as usual in the boot process.
;
; Input: nothing
; Output: D0.W = non-zero if no ROM disk was found or if one was it was non-bootable
; D0.W = zero means we found a bootable ROM disk. The code in the ROM disk
; already called FinderStartupDevice.
