I don't suppose there is a way to use testbios with a system having 2 video cards is there?
I need to try and make this work.
I've sucessfully run the new emulator on my PCI dev card in a desktop system with the PCI card as its only display and received a bios init message. Yah! The most progress I've had in weeks since ATI's tech help is proving to not be so helpful.
It still does not work on my target system. Going over the IO dumps between the 2 systems I find that some of the ins get different info and then the bios does different stuff. Some of the bits that are different are CRT enabled bits.
So my guess is that based on if the CRT is already up (ie warm boot) the BIOS takes a differnt path than that of a cold boot.
So I really need to run the emulator on my PCI card with only a POR.
What I'm currently doing is using setpci to disable the primary mem and IO responses and then enabling the secondary card. This is the same method I used in my previous bios setup to init 2 video chips. Just in the BIOS at boot time rather than from user space.
Then I run testbios.
I'm running it from a remote ssh login because it dosn't seem to work properly if I run from a console session.
Anyway it does something differnt and does not init the card. However its not the same as what it does on my target. I'm still reviewing the io log files.
Any reason why the enable/disable via setpci might not work from user space like does in BIOS land.
