Well i learned something new today. Old XL hardware requires the I/O board connected to boot from cdrom drive. Before i connected the I/O, i connected a hard drive with dos on it and it booted into dos. But when I connected just the dvd drive it wouldnt boot from the disc. I just assumed boot from cdrom was disabled in the bios. But without a ps2 keyboard i couldnt test that theory. So listening to you guys talking about that u12 chip on the I/O board i figured what the hell and connected it. It now boots from a XL platinum cd I have in the dvd drive.
Now I can play around with some of these "MEGACDLL.EXE" files. >:D

I can dump u12 and u13 with a Willem programmer.
found this in one of the XL manuals:
U12 - EPROM – This is the operating system for CD-ROM based games and is classified as Drive C:\
ed12, does u12 contain code to read from CDROM? If so, can it be changed to read from a CF card? Playing around with the main exe and want to be able to make changes without burning a new disc everytime i make a change.
Im sure i will find out soon enough, but my Willem is db25 and I need to dig out a very old mobo with a db25 printer port. Might just open one of my RX motherboards but i think im out of ddr2.
