Bugs[edit | edit source]

Installing on newer processors[edit | edit source]

This version has a bug in the keyboard driver that causes setup to crash loading with TRAP 0000 due a division by zero when installing on any processor faster than a 486 processor. To install on a faster processor, the BASEDD0x.SYS files must be patched to remove the sequence that causes the division by zero.[1]
