Sorry I mean the complete canyonlands codes which calls pci_run_vga_bios(). I see currently pci_run_vga_bios() is only called by chromebook_link. And do you think the int15_handler() required by the biosemu needs to be common? > Re your other question I was looking for the VGA enable bit, as I > remembered it from years ago.

I doubt the VGA enable bit only affects x86 as it opens the A0000 and I/O address decoding which is only applicable on x86. > For the ROM, pci_rom_load() works for me, after pciauto_setup_rom() is > called. I wonder if you haven't enabled the ROM BAR? I initially got > the same result as you. Yes, I called pciauto_setup_rom() in my codes. I also verified the expansion ROM address register has bit0 set to 1 which means enabled.
