I've run across an interesting problem in some GS/OS software I'm writing. If the program crashes or I try to exit via a control-reset reboot I can't boot the system off my CMS 60 hard disk attached via the CMS SCSI card unless I power down the machine for a minimum of about 5 minutes.. sometimes longer. The program has an interrupt handler and all but you'd think that a ctrl-reset or even a brief power down should take care of this sufficiently. I can boot off the 3.5 disk so it makes me wonder if there's not something funny in the way the GS/OS drivers handle the CMS ROM based driver and perhaps there's something on the CMS SCSI card or hard drive that you can kill for awhile even with the power off. Anyone have any clues on this?

A couple of thoughts come to mind. Are you also powering down your CMS-60 when you power down your GS? It appears there maybe enough power coming through the CMS SCSI card to hold some memory in the GS. Also there is a problem with some of the main chips on the CMS card. If yours should be a Mitsubisi (sp??) chip, contact CMS for a FREE upgrade chip. The bad ones have a timing defect problem that can affect many things including the boot sequence, not allowing the use of some other cards such as a Fingerprint GSI card, etc. I obtained my free upgrade chips for my CMS drives at the last Applefest and everything works just fine now. Hope the above is of some help. -- Internet -- bsherm%umbio@umigw.miami.edu UUCP -- {uunet!gould}!umbio!bsherm Miami's Big Apple 305-948-8000 1200 baud 24 hours 8 years online
