Hi, We have designed a VME CPU card based on IBM Maple platform. We've had problems making it work with a PCI/PMC graphic card we've also designed based around the ATI Radeon 7000 (RV100 QY). To solve this we have linux consultants helping us in emulating the ATI video BIOS at the linux kernel level. But we would like to modify the PIBs firmware with simple routines (scroll,..) to use the graphic screen attached to the ATI as a text (alphanumeric) console. The keyboard would be USB. Is this possible even if the video BIOs didn't previously initialize the ATI graphic chip?
If the BIOS hasn't initialized the chip, you are pretty much out of luck... The good news is that soft-booting an rv100 with the BIOS works fine, at least from my previous experiemnts with it.
I realize this question doesn't re ally belong here...but not sure where to ask, sorry about that. Thanks a lot -jf simon ___________________________________________________________________________ Yahoo! Mail réinvente le mail ! Découvrez le nouveau Yahoo!
