Ok, I'm STILL getting lockups. Had to put the WSPro aside for a couple months and just got back to it last week. Put her all back together, formatted an old 850 MB Maxtor and installed 98 on it along with 98lite Professional. Stripped everything except for Media services and networking off. Had to leave IE so I could get drivers and such though.
Using an old ISA Multi-IO card to run the HD, everything else on it disabled. Network is through a SMC-2202 USB adaptor. I have nearly everything turned off in the BIOS including the serial ports, parallel, HD block mode, etc. I've changed the clock multiplier on the RAM and that seems to have helped some. I'm using the modified BIOS that was floated around (can't remember the name).
Ok, things will run fine for a while and then all of a sudden : BOOM. complete lockup. I tried doing the "remove everything and let Winblows re-detect" but when I do that I still get stuck with the IRQ steering thing on 15 (where the USB lives). How the hell do you get rid of those?
Basically, I'm totally stumped and very frustrated. I want to use this as an MP3 player, but it's pretty much useless to me if it keeps locking up like this.
