ollie,
can you look at that?
I will check this one later.
Also static void *pci_ram_image_start = PCI_RAM_IMAGE_START;
should be changed to static void *pci_ram_image_start = PCI_RAM_IMAGE_START + 0x10000;// leave first 64k for VGA
No. There are to #define constants:
#define PCI_RAM_IMAGE_START 0xD0000 #define PCI_VGA_RAM_IMAGE_START 0xC0000
I already reserved 64KB for VGA BIOS.
