Ever since I got my 2091 I have been getting Random gurus from 2 addresses. Just recently I have tracked the addresses to the SCSI Handler and the IORequest Handler. When I get these gurus Location 0 has these numbers in it (as shown by MemGuard) 48454C50 which translates to HELP in ASCII. I am using FastFileSystem Version 1 Identifier Ox444f5301 that is 12248 bytes long. My dealer has been unable to determine why I get these gurus since they don't happen consistantly. I get gurus when doing SCSI I/O and when the system is just sitting there not doing anything. I have Wshell, Conman, Fcomp, AREXX and Crossdos in my startup-sequence but when I removed everything but CBM supplied programs I still got gurus. My Hardware is an A2000 V4.2 Mother board with the missing first keystroke problem fixed, 1.3 Roms, Fat Agnus, Micron 2 Meg Memory board, AT Bridgeboard and 2091-40. If my problem sounds familiar to you and you found a cure please let me know. Thanks in advance!

My only suggestions: try board-swapping the 2091 and/or the motherboard. Also, you didn't indicate what versions of the roms you had, but I know of no version that causes that sort of error. Actually, before board-swapping, I'd remove all other peripherals - it could be caused by some sort of Zorro problem between the 2091 and one of your other boards (micron, AT bridgeboard). >My Hardware is an A2000 V4.2 Mother board with the missing first keystroke >problem fixed, 1.3 Roms, Fat Agnus, Micron 2 Meg Memory board, AT Bridgeboard >and 2091-40. -- Randell Jesup, Keeper of AmigaDos, Commodore Engineering. {uunet|rutgers}!cbmvax!jesup, jesup@cbmvax.commodore.com BIX: rjesup Disclaimer: Nothing I say is in anything other than my personal opinion.
