Over the past year, I have built 6 systems running SCO OpenServer 6.0.0 using this board, However, the latest two boards do not work.
The microcode level is 28, and the AA numbers end in 207, and the BIOS is rev 110.
The problem is that after the system boots, the display is corrupted. I believe that the operating system is written using 7 bit ascii, but the display shows characters with values from 128 to 255, instead of 0 to 127.
My question is, can I resolve this by reverting to bios revision 44 (used with AA -206, and microcode level 26)?
