Re: ATI Rage XL with no BIOS support

[Jay Cotton <Jay.Cotton@Sun.COM>]

Basically you are screwed.

There is a way to fix this, but the code is closed source and ATI will not
allow it out of there control.  So, unless you can read the bios prom
into memory and execute the first 1024 bytes in 16bit mode, you will not
be able to recover.

sorry
