Greeetings!
As I posted earlier, I can't seem to quit from vp/ix. Thanks to Dave
Goodman I tracked down the heart of the problem. It is my video. In confirming
this I discovered a very weird bug... My machine will quit from vpix as long
as it is attached to a color monitor! My mono just won't cut it. Sounds
like black magic to me. If this makes any more sense to any of ya'll I would
GREATLY appreciate any pointers.
-Thanks
-Dave

Then I changed over to a Paradise VGA+ and a Seiko VGA monitor. I can enter VPIX and run DOS programs, but when I quit, the screen goes away and can't be recovered except by a hardware reset. The VGA system works fine under Unix. The VGA system works fine under VPIX. But leaving VPIX crashes the display system. Note that I actually do return to Unix and can switch virtual terminals to console and run shutdown, but of course I'm working blind until a hardware reset. I suspect that the display card is being switched to a TTL mode, probably EGA, when it returns from VPIX. The Seiko in an analog only monitor and goes into sweep protect when exiting VPIX. Does anybody know a fix for this problem? Gary

In my box I used an Ati VGA-Wonder 512k with mouse connected with a TTL monitor and got monochrome EGA. In dos I was able to boot it as anything up to but not including VGA with no problem. Interactive's UNIX (2.2.0) is not as forgiving and it would only boot up, ie install, if I locked the card in hercules mode, but at least it worked. VP/ix (1.2.0) on the other hand would not come up until I commented out the VGAROM and EGAROM entries. The most serious problem with the ati combo (besides that I never got the mouse to work) was that if I changed windows from VP/ix to anything else I would not be able to change back. When I tried to return VP/ix would try for a while and eventually just beep at me and just sit there. So I ripped the ati card out and slapped in an old mono/herc card and now VP/ix works fine. My assumption was that VP/ix would start in mono mode and work fine, but when returning from another window it (or the kernel) would get confused and think it was in colour and try to restore that window, but unsuccessfully. My suggestion would be to check how "compatible" the vga card and monitors are. Ati's monochrome ega on a ttl monitor is a nice feature, but it is not standard in the register level, so I'm out until I can get a colour monitor. Your mileage may vary, but it sounds very familiar... -- Jose Dias jad@nyama.UUCP Who me? I didn't say anything!
