;
; Change History (most recent first):
;
; <SM10> 10/25/93 SAM Roll in <MC2> from mc900ftjesus.
; <MC2> 10/25/93 SAM Changed InitUtil to explicitly set the memory manager PRAM
; location to a nonzero default (Figment on, 32 bit heaps).
; Changed the default mouse speed setting from 2 to 3.
; <SM9> 6/21/93 SAM Changed the comparison in _Delay to be unsigned (ugh) and bumped
; the default disk cache size from 32 to 96k.
; <SM8> 6/14/93 kc Roll in Ludwig.
; <LW2> 6/11/93 chp Replace the Reliability Manager’s Time Manager task with a
; _DTInstall of the original task code. It is better to call
; _ReadXPram and _WriteXPram with interrupts enabled since
; interrupts are used to communicate with Egret/CUDA.
; <SM7> 1/29/93 RB Made the Delay trap compatible with NuKernel by changing the way
; it uses the status register.
; <SM6> 10/18/92 CCH Added NoSound conditional for build-time zeroing of volume.
; <SM5> 9/28/92 RB The old Sound Manager used to update the low mem global
; sdVolume, but the new one does not. So I chose the ReadPram and
; WritePRam routines to update sdVolume after the volume level is
; changed by the Control Panel, which writes PRAM. Removed the
; NoSound code used for Cyclone bringup.
; <SM4> 6/29/92 RB Re-enable sound for the New New Sound Manager.
; <SM3> 5/28/92 kc Roll in Horror Changes. Comments Follow:
; <P3> 5/13/92 KW (HJR,H7) Fix problem in InitCPHardware where it was calling a
; RAMless routine without having the return address in A6.
; <P2> 02/12/92 jmp •••Temporarily set the default sound volume to zero to effectively•••
; disable sound on Cyclone.
; <H6> 11/12/91 jmp Just went back and marked my previous change.
; <H5> 11/12/91 jmp Changed the pRAM table to default to having the color desktop
; pattern enabled for CQD-capable CPUs.
; <H4> 11/6/91 SWC Re-wrote clock and PRAM routines to be table-driven so that
; future expansion should be really simple (and clean). Hardware
; dependent routines will now be found in ClockPRAMPrimitives.a.
; <H3> 10/18/91 SWC Exported ReadTime so the ROM will link (changes in progress
; caused a little problem with sources out of sync).
; <H2> 8/6/91 SWC Modified ReadPRAM and WritePRAM so they use extended PRAM calls
; to get the original 20 PRAM bytes.
; <SM2> 5/21/92 kc Append "Trap" to the names of
; SysEnvirons,WriteParam,ReadDateTime,SetDateTime,UprString and
; RelString to avoid name conflict with the glue.
; <10> 9/9/91 JSM Cleanup header, use SysEnvirons stuff defined in SysEqu.a
; instead of redefining it here.
; <9> 6/12/91 LN Changed #include 'HardwareEqu.a' to 'HardwarePrivateEqu.a'
; <8> 7/23/90 MSH WriteParam did the read back verify all wrong.
; <7> 3/22/90 MSH SysUtil and Clock rewritten to place all hardware dependent
; routines in clock and to remove redundant parameter RAM reading
; and writing routines. Also added Waimea versions of these
; routines.
; <6> 2/28/90 GMR Made changes for Egret code to match new Egret equates.
; <5> 2/10/90 GMR Put in temporary fix for Egret, using Wr6805Addr instead of
; WrPram.
; <4> 2/5/90 GMR Added Egret clock support to ReadTime, WriteTime, and ReadPram,
; WritePram, making them universal.
; <3> 1/3/90 CCH Changed Gestalt equate filename back to GestaltEqu.a.
; <2> 1/2/90 CCH Changed name of Gestalt equate file.
; <3.7> 11/13/89 MSH Pmgr equates now in record format.
; <3.6> 8/28/89 PKE Delete LwrString from this file and just use the one in the
; Script Manager file ScriptMgrPAtch.a (same code, no sense in
; duplicating it here; should have done this a long time ago).
; Also delete include of PackMacs.a, ScriptPriv.a.
; <3.5> 8/27/89 PKE Deleted local newItl2Tables symbol (used for LwrString, was set
; to 1 here) and cleaned up conditionals based on it.
; <3.4> 8/24/89 PKE FOR F-19, WE SHOULD DO CHANGE #2 HERE: Rolling in changes from
; patch files: (1) Change LwrString to save IntlForce flag then
; clear it before IUGetIntl call, restoring it afterward. This is
; so we get the itl2 tables for the correct script (instead of the
; tables for the system script). (2) Put UpperTab bug back in (was
; removed in 1.5) so file system sorting via RelString works on
; old volumes.
; <3.3> 8/22/89 SES Removed references to nFiles. Changed EnvBadSel & EnvSelTooBig
; to EnvBadVers and EnvVersTooBig.
; <3.2> 8/9/89 CCH Changed gestaltQuickdrawType to gestaltQuickdrawVersion.
; <3.1> 7/16/89 CCH NEEDED FOR AURORA: Made SysEnvirons check Gestalt error codes.
; <3.0> 7/8/89 PKE NEEDED FOR AURORA: Fixed error code returned by LwrString if
; 'itl2' not found.
; <2.9> 6/20/89 SWC Changed default mouse tracking from 0 (tablet) to 3
; (medium-slow) so the mouse won't move like a slug when parameter
; RAM gets reset. Also to make Ed Birss happy, I hear.
; <2.8> 6/14/89 SWC Missed an '@' on a label. I know: "bad dog!"
; <2.7> 6/14/89 SWC Exported PRAMInit and PRAMInitTbl so they can be used by
; ValidatePRAM (Clock.a). Reformatted the PRAMInit table to make
; it more readable. Cleaned up code.
; <2.6> 6/5/89 PKE In LwrString, add more error checking after IUGetIntl call and
; set error return if necessary.
; <2.5> 5/25/89 CCH Revised again to deal with new Gestalt equates.
; <2.4> 5/25/89 rwh added the aptly named Reliability Manager
; <2.3> 5/24/89 GGD Converted to feature based conditionals.
; <2.2> 5/23/89 CCH Added check of Gestalt return codes to detect unknown results.
; <2.1> 5/18/89 CCH Updated SysEnvirons to use new Gestalt interface.
; <2.0> 4/16/89 CCH Changed Gestalt equates to new prefix convention.
; <1.9> 4/7/89 PKE Updated LwrString to use noMarkListOffset instead of
; lowerNoMarkListOffset.
; <1.8> 3/28/89 PKE Use OS trap bits 9-10 to control function of LwrString
; <1.7> 3/6/89 CCH Fix some minor bugs in SysEnvirons.
; <1.6> 3/3/89 CCH Gutted SysEnvirons, and replaced it with calls to Gestalt.
; <1.5> 3/1/89 PKE Save & restore a2 in LwrString; fixed err in UpperTab (UprString
; gave 'a' as the uppercase of '`').
; <1.4> 2/28/89 PKE Revert UprString to version from Mac IIx ROMs, which doesn't
; move memory or depend on a5 world (the planned version could
; have done both).
; <1.3> 2/21/89 PKE Fix LwrString/UprString to get char class & case conversion
; tables from itl2, not itlR (itlR is going away and these tables
; are being moved to a newly extended itl2). Note: changing
; UprString to get tables from any resource could break apps, so
; it will be reverted to to an old, non-International version as
; soon as I find the old source. All the Intl stuff will be done
; thru enhancements to LwrString.
; <1.2> 1/16/89 GGD Added a scratch register parameter to the BigJSR macro calls
; since it will be needed when they change to use PC relative
; addressing.
; <1.1> 11/10/88 CCH Fixed Header.
; <1.0> 11/9/88 CCH Adding to EASE.
; <1.2> 10/27/88 PKE modified by Carl Hewitt and Brian McGhie as part of the process
; of putting Script Manager in ROM

; <C919> 10/27/87 MSH Bug fixes and added a retry to writetime.
; <C881> 9/3/87 MSH Port to HcMac (Laguna). Also removed some leftover trash at the
; end of the file.
; <C774> 2/9/87 SHF Changed parameter RAM initialization value for boot device: now
; defaults to SCSI ID 0 (internal).
; <C551> 12/19/86 GWN Extended PRAM init table.
; <C518> 12/12/86 GWN Replaced 'Bugs' with 'NuMc' to determine when PRAM is to be

; The Reliability Manager

; and recording pertinent information in parameter RAM.

; InitReliability - sets time of 1st power on, and initializes the Usage Statistics time
; manager task
;
; The time of 1st power on is kept as the number of 48 hour periods since Jan 1 1989. To
; calculate this, we first get the number of seconds since Jan 1 1989. On 020 and higher
; machines, we could divide by the number of seconds in 48 hours. To work on 68000
; machines, we separate out factors of two to get the divisor into the 16 bit range:
;
; # 48 hrs since Jan 1 1989 = (# secs since Jan 1 1989) / (# secs in 48 hours)
; = (# secs) / (60 * 60 * 24 * 2)
; = (# secs) / (2*2*15) * (2*2*15) * (2*2*2*3) * 2
; = (# secs) / (15 * 15 * 3) * 2^^8
; = ((# secs) / 2^^8) / (15 * 15 * 3)
