PROBLEM SOLVED !!?! The problem was a buggy BIOS, that won't properly turn off PnP (Flog'n'Fail). I ordered 2 of the last remaining VTI (Vextrec) GMB-P541IPS v0 motherboards. (They are being discontinued). The VTI uses the AWARD V4.50PG BIOS, and the menu has proper places to turn off PnP. I am now running with a P133 instead of a 486DX50. Life is good... The TYAN motherboard that was giving me fits is VERY SIMILAR - but not the same - and uses the AWARD V4.51P6 BIOS, which lacks the explicit PnP turnoff feature. PnP apparently interferes with the Adaptec 1542B's interrupts. I will contact TYAN and see if I can get an older version of the BIOS, and see if it fixes the Tomcat. Until then, *** AVOID the TYAN S1562 Tomcat motherboard with AWARD BIOS. *** Unfortunately, this board is the only 5 ISA slot Pentium motherboard still in production, besides the QUICKTECH built-in-SCSI motherboard. If you are considering upgrading your systems from 486's and want to keep your old boards and configuration, buy some of the last VTIs or pressure TYAN to fix their BIOS. Meanwhile, if anyone has a time machine handy, I would like to go back in time and deliver packages of condoms to the parents of the twits that invented PnP. GRUMP! Keith PS - Note to BSDI - I still have the TYAN. Would you folks like to borrow it for a while and see if it behaves strangely for you? I am not currently under support, but I wouldn't mind contributing to the general advancement of BSDI anyway. BTW, I built an experimental 2.0 disk, and the boot error occurs in the exact same manner. I also see some errors with DOS 6.2, though those are more subtle. -- Keith Lofstrom keithl@klic.rain.com Voice (503)-520-1993 KLIC --- Keith Lofstrom Integrated Circuits --- "Your Ideas in Silicon" Design Contracting in Bipolar and CMOS - Analog, Digital, and Power ICs
