Subject: Re: problems with VESA driver

As pointed by CB, not ALL of VESA BIOSes (or BIOS overlays) have
nice behaving bank switch functions. After testing several cards I
assumed that original function, although designed for real mode, can
work in protected 16-bit mode. Unfortunately this is not always true
- in some cards the function references BIOS data segment, which causes
bank switch to fail with GPE. This will be fixed by DJ, CB and/or me
in the next release of GO32 and VESA driver.
