for my debugging do you think 8124M would work with X11SPM and bios 3.9 or 4 so I can try swapping between them (8124M and 8259CL) for debug? My other chip is a ES that requires v2.0a to work so probably normal that it will not post with bios of 3.9 and 4.0 modded or notnow updated the GUIDE for BIOS 4.0
