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 when loading with TRAP 0000 due to a division by zero when installing on any processor faster than a 486 processor. To install on a faster processor, KBD01.SYS must be patched to remove the sequence that causes the division by zero.[1]
Processor reset[edit | edit source]
The setup in this version also utilizes a processor reset sequence to change from protected mode to real mode. As a result, most hypervisors such as VirtualBox will crash when the processor resets due to a triple fault. It is necessary to enable resetting on triple fault on hypervisors that support it to allow setup to load.[2]
