-LinuxBios Guy's OK, well if Intel won't play nice then i will have to see what i can do by back tracking a stock 855GME bios... Do-able, but a pain. I am going to try to get linuxbios installed on a LV-671 motherboard... I will keep you guy's informed as to how it goes. If you have any ideas, please pipe up. Thx -Adam Talbot

PCI VGA card works too
by Li-Ta Lo 11 Jan '05

11 Jan '05

Hello, I just made PCI vga cards works too. The problem is if the PCI card does not claim PCI IO resource, the bridge's IO enable bit in the command register is not enabled. Even with the legacy forwarding enabled in the bridge control, it still does not forward any legacy vga io. So the pci_bus_enable_resources() should be void pci_bus_enable_resources(struct device *dev) { uint16_t ctrl; /* enable IO in command register if there is VGA card * connected with (even it does not claim IO resource) */ if (dev->link[0].bridge_ctrl & PCI_BRIDGE_CTL_VGA) dev->command |= PCI_COMMAND_IO; ctrl = pci_read_config16(dev, PCI_BRIDGE_CONTROL); ctrl |= dev->link[0].bridge_ctrl; ctrl |= (PCI_BRIDGE_CTL_PARITY + PCI_BRIDGE_CTL_SERR); /* error check */ printk_debug("%s bridge ctrl <- %04x\n", dev_path(dev), ctrl); pci_write_config16(dev, PCI_BRIDGE_CONTROL, ctrl); pci_dev_enable_resources(dev); enable_childrens_resources(dev); }

The ATI card has PCI IO resource so there is no bogus resource in the northbridge. As the Nvidia card it does not have PCI IO resource so we got the 20000 to 1ffff thing. Ollie

RE: Enable apic ext id to use 256 apic id for AMD64
by YhLu 11 Jan '05

I don't think it is caused by the change about nodeid. In s2885, it only change lapicid() to lapicid() & 0xf, and will not affect non apic lifting problem. What't the card that you are using on S2885?, and If I get time, I would try that on s2885.

For dual core and lifting apic id, you can not just use apic id as node id. And you have to use Lapicid() & 0xf Or cupid to get it.

PCI Expansion ROM POST committed
by Li-Ta Lo 11 Jan '05

11 Jan '05

Hello, I just committed the VGABIOS support. It works for some ATI and Nvidia card. Currently it will try to POST any PCI card it can find with PCI expansion ROM. I will add the #ifdef PCI_EXPANSION_ROM or if (class == vga_class) later. Ollie
