Re: Q: help disassembling old driver

[david lindauer <dlindauer@xxxxxxxxxxxxxxx>]

sven,

    I looked briefly at the code and the DIP driver appears to rely on a BIOS
extension existant on that computer.  So I don't know how far I can get with that
version... the HP driver doesn't use that stuff.  Is there any way you can find out
what chips are used on these boards?  Possibly we may be able to scrounge up the
manufacturer's documentation...
