Message-Id: <403256E6.6000705@ngi.it> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-hotplug@vger.kernel.org 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?
