I'm now convinced the chips in the OP are fake. I ended up grabbing a legit 20MHz part

http://www.xtideuniversalbios.org/binaries/ It's not a custom BIOS, just an option ROM that takes over disk handling from the system BIOS. Something to maybe try down the road once you've got a stable foundation

The XUB can allow you to boot from other IDE drives at boot time through the boot menu. You could just install each drive with the OS as normal separately, and then connect one of them as secondary master or a slave and use XUB to boot from it when desired.

getting PCI IDE or SATA controllers to work properly in motherboards that have onboard controllers is always an exercise in frustration. I'd remove the card completely for testing purposes BTW I love the CRT so much

Seeing as how you're having all these goofy issues, I would realllllly recommend trying an install on a bog standard IDE drive using the motherboard's onboard controller, if applicable.

Windows 2000 Pro is a great OS in its own right, but it is most certainly NOT built on DOS. It's true NT kernel. You might as well go with Windows XP

So it was just a bad PAL all along. I'm up and running! Dreamblaster was nice enough to send a replacement free of charge, and he also threw in 2 more PALs and an awesome little MT-32 music box with the monkey island theme!! What a guy!

It could be that the clock for your DMAC is derived from that xtal, which would explain the floppy issues

So.. what is the point then? You might as well just run a long floppy and power cable outside of the case and use a standard floppy drive if that is the case. I am guessing the OP is wanting something that can easily be used on different systems without having to either have a special ISA card or …

IBM 4869 and 4865 are what you seek The IBM ones require a special ISA controller card though so not exactly standard. nothing really "special" about it other than it had the DC-37 connector on the back plate you can use these drives on any FDC if you make your own cable by crimping an IDC Female …
