[mod.computers.vax] More on VAXEMUL.EXE

jeff@VAXA.ISI.EDU (Jeffery A. Cavallaro) (07/29/86)

To recap:  One of our clustered 750s refuses to boot due to SYSBOOT complaining
about a missing instruction emulation file: VAXEMUL.EXE.  This file is not
present on any of our other non-clustered VAXen.

More info:

After consulting the fiche, it turns out that there are four instructions that
will cause this file to be loaded if they fail via OPCDEC or emulation faults:

		MATCHC
		DIVP
		EDITPC
		CRC

Upon running the instruction diagnostics, MATCHC, DIVP, and EDITPC are listed
and pass, but CRC is never listed.  We ran diags on a working 750 on the same
cluster (which reboots fine), and it doesn't report CRC either.

Just for fun, we then ran the floating point diagnostics.  The diags claimed
that G,H-floating options were not present, but then ran such tests anyway
that passed.

I have looked all through our current systems, backups, and some past
installation kits.  They all seem to contain FPEMUL.EXE, but none contains
VAXEMUL.EXE.

Does anybody know what is going on here?  Are the diagnostic trace messages
just not complete?  Is this ONE instruction (CRC) bad???

Any suggestions welcome,
Jeff.
