[Vgabios-developers] VBE should not use 0xff80 indexed ioport

[Daniel Gimpelevich]

Bochs gives the following error trying to access the DISPI interface:

allow_io(): IO adr ff80 outside TSS IO permission map (max port=416) 
#GP(0)

Furthermore, the 10th, 11th, 12th, and 13th editions of Scott Mueller's 
very good book <http://www.m-tr.com> all list the 32 bytes beginning 
with ioport 0xff80 as expected to be used with the Universal Serial 
Bus, which Bochs now emulates. I have recompiled both Bochs and the 
VGA-BIOS to use 0x1ce and 0x1cf, like the VGA-BIOSes from ATI, but I 
don't have cvs write access to the Savannah compile farm. It really 
should be part of the Bochs cvs tree. Now if I could only get X11 under 
Bochs to work in VESA mode instead of just showing a black screen...	-DG
