Fake Video Bios. How?
Hi all,
I want use a VTBook card (www.villagetronic.com) with XFree86 4.3.0. This card is based on Trident XP2 graphics chip.
Note that:
- this graphics chip is currently unsupported by XFree86. I use the "vesa" driver;
- graphics card is based on Cardbus (32bit PCMCIA);
- card does not include video BIOS onboard. Bios must be loaded after hotplug event.
- I have got the binary image of BIOS (VBE 2.0 compliant)
I tried some XF86Config Options such as:
Option "BiosLocation" "address"
Set the location of the BIOS for the Int10 module. One may select a BIOS of another card for posting or the legacy V_BIOS range located at 0xc0000 or an alternative address (BUS_ISA). This is only useful under very special circumstances and should be used with extreme care.
Option "BiosBase" "address"
but they are not the solution.
I tried to map /dev/mem and put a copy of video BIOS in V_BIOS (0xC0000) before running X, but this way was not successful.
How soft boot secondary cards if they have not a video BIOS?
Do you know some utility to load bios in a way ready to be used by XFree86? Any idea?
Thanks in advance,
Guido
