; Change History (most recent first):
;
; <18> 6/12/91 LN removed #include 'HardwareEqu.a'
; <17> 3/4/91 dba dty: get rid of SysVers conditionals
; <16> 2/7/91 dnf kst, #79676: Use dsRecoverVCBPtr to draw the name of the volume
; that we're attempting disk recovery on.
; <15> 1/14/91 stb & mda; Add culprit name to generic crash dialog
; <14> 1/14/91 stb & PKE; tweak error messages; restore A5, SR, and SP for forced
; exits and clear MacJmp to prevent reentrancy <dfh>
; <13> 12/15/90 stb & KSM; improve the dsBufPtrTooLow message. add a <dfh> change to
; DoExitToShell to clear debugger flag. add a template for
; dsMemFullErr which show INIT or app name.
; <12> 11/21/90 csd & gbm; Remove the conditionals around the non-Shutdown manager
; code because we still need it for errors that happen before the
; Shutdown Manager is installed.
; <11> 11/15/90 stb & JDR; add alert for dsBufPtrTooLow
; <10> 9/6/90 DTY changed the wording of the shutdown messages. The old message
; seemed to imply that there was a safe and an unsafe way to turn
; off a Macintosh.
; <9> 6/11/90 DDG NEEDED FOR SIXPACK: Fixed previous comment.
; <8> 6/11/90 DDG NEEDED FOR SIXPACK: Fixed the dsNoFPU error to not spill over the
; end of the dialog.
; <7> 6/1/90 PKE DARIN IS A BAD DOG. In <5>, he changed the symbol name
; UImpTrapNumber to UnimplementedTrapNumber, but didn’t change the
; reference to it, thus breaking the SixPack build. Fixed it.
; <6> 5/31/90 DDG Added a generic system error (dsNoFPU) for ericksons and elsies
; that don’t have floating point chips.
; <5> 5/30/90 dba add alert for forced quit
; <4> 1/30/90 dba get rid of warnings when assembling; put in fancier messages;
; fix bug #34819 by reaching down the stack to restore the value
; of CurMap for the convenience of applications with ResumeProcs
; <3> 1/12/90 CCH added include of “HardwarePrivateEqu.a”
; <2> 12/28/89 dba changed PROC to MAIN so we get dead code stripping; got rid of
; the grayed resume button
; <1.4> 10/11/89 dba reformatted file; added new ShutDown Manager “user choice”
; alerts; improved icons
; <1.3> 8/15/89 dba OK FOR 6.0.4: get rid of Resume button in “can’t load the
; application: Finder”
; <1.2> 8/11/89 dba NEEDED FOR 6.0.4: changed text for alerts; improved ShutDown
; code used when ShutDown Manager is not present; added duplicate
; button lists to handle case where ResumeProc is not NIL; added
; system version to text of some alerts
; <1.1> 5/15/89 CCH Added alert for memory parity error. (#101)
; <1.0> 11/16/88 CCH Added to EASE.
; 8/16/88 dba changed procs 98 and 99 to avoid collision with errors 98 and 99
; proc 98 is now proc 1098; proc 99 is now proc 1099 this caused a
; crash after “force-launching” a document from the Finder
; 3/20/88 EKH Added SysErr #98 (dsNoPatch) for RomNoPatch, so it has it's very
; own SysErr number.
; 1/7/88 EKH Added Alert for "needed resource can't be loaded" error at boot
; time (SysErr #99). This error is generated by PTCH id -1, and
; anyone else who can not load a "do or die" resource from the
; system file. <S355 EKH>
; 3/30/87 jdt Moved HD20 startup alert here from the boot alert table.
; 3/5/87 LAK <S088> Launch errors (System Error ID 26) modified to explain
; that the application could not be opened and allow return to
; Finder. Specifically, added Alert 26, Text 47, Icon 39, Procs
; 98-99, Button List 74, and String 81. Changed ShutDown alert
; text from “power off your machine” to “turn off your Macintosh”;
; it now shares icon 39 with launch fail alert. This file may now
; be built as an INIT 31 file for testing (see below for sample
; build code).
; 12/1/86 jdt Removed the installation code as this is now a DSAT resource.
; 9/9/86 DLD Changed the PowerOff Icon's bits.
; 9/3/86 DLD Made Reset call ShutDown if Possible.
; 9/3/86 DLD Added the ShutDown Alert
; 9/2/86 DLD Added Align 0 before ResumeString to avoid word alignment on new
; assembler.
; 8/4/86 DLD Converted source to MPW.
; 4/14/84 SC mercilessly chopped out stuff, added RESET
; 2/23/84 AJH tweaked disk switch alert
;
; NOTE: UserAlerts is loaded before PTCHs on Mac Plus and SE ROMs ($75 and $276).
; (BootAlerts is active while PTCHs are loaded on all other ROMs.)

; Icon numbering:
;
; The internal icon numbers are also used as resource IDs for color icons,
; so they must be assigned like all other reserved resource IDs.
; Also, like all the other numbers below, they must steer clear of system errors.
; For this reason we use negative numbers lower than -10000.
