Hmm... Let me back up a step. I'm apparently answering a question you're not asking. Your problem is that you want to disable the internal video (and PCI header) and use external, right? Is that it?
Yes, but Not really external, the "onboard" Cyberpro 5000 graphic chipset looks like a integrated pci card with own memory. I guess external is the right word for that :D
Under factory bios, the device 00:12.4 is not shown with lspci. We know, that it is possible to disable the special graphic instructions for the Geode CPU, but I think 00:12.4 is the integrated graphic stuff at the southbridge cs5530. So, is it automaticaly disabled, when the Geode Graphic stuff is disabled or is there a magic bit for the cs5530 itself?
However, it would be fine to totally disable device 00:12.4
Our current main problem is the slow coming up "external" vga device. It takes around 90 seconds to initialize this device under LB with the emulator.
Our preferred settings for this platform were:
BC_XMAP_1 = 0x1300C060
That could help, currently is it set to 0x60
BC_XMAP_2 = 0x09999999 BC_XMAP_3 = 0x99****99 (* = don't care)
Or perhpaps just confuse things more. 9's in XMAP2 is PCI accessable, No Cache, No Write, Read.
What about CPU revisions, could it be that this registers have changed in the time? I guess, I use an older datassheet.
