HP Vectra VLi8 (intel 440bx)
by Mike Jackson 14 Jan '05

14 Jan '05

Hi, I just bought 5 old vectra vli8 500 Mhz P3 boxes to build a cluster with for learning purposes. I obviously don't want to be dragging out my spare monitor every time I want to change something in the BIOS. As far as I can tell, they have the Intel 440bx motherboard. I am unclear as to whether this board is supported or not. The status page says: This is a template for generic 440bx boards, see the smartcore-p3 digitallogic/smartcore-p3 stable Ron Minnich rminnich(a)lanl.gov 16/12/2002 Now works as of current CVS digitallogic/smartcore-p5 stable Ron Minnich rminnich(a)lanl.gov 01/06/2002 I have no idea if my Intel 440bx boards are "digitallogic/smartcore". Please advise if I can use LinuxBIOS or not. Also, please advise if you know how I can change the BIOS settings remotely using open-source tools. The cluster nodes are running freebsd 5.3. Thanks, Mike

CONFIG_PCI_ROM_RUN added in Option.lb #if CONFIG_PCI_ROM_RUN==1 And #if CONFIG_CONSOLE_VGA==1 Added in device.c pci_device.c and pci_rom.c and Config.lb in src/devices Also console/vga_console.c modified. YH

The amd_setup_mtrrs that is called by model.... cpu init is right.... So make the amd_early_setup_mtrr work right as later one....

I don't know how to fix this execpt rewrite the whole early_mtrr. Probably we should add a dev_post() pass and put the ROM post into device_op::post? Ollie

Then Eric need to fix the MTRR for AMD...? -----Original Message----- From: Li-Ta Lo [mailto:ollie@lanl.gov] Sent: Friday, January 14, 2005 6:58 AM To: YhLu Cc: Sagiv Yefet; LinuxBIOS Subject: RE: Running with VGA On Thu, 2005-01-13 at 22:20, YhLu wrote: > The problem is no body touch that range.

The amd/early_mtrr does not enable MEM forwarding of A0000-BFFFF to main memory and amd/mtrr is called to late (it doesn't check if A0000-BFFFF should be forward to IO or MEM neither). I fixed it a long time ago. Eric's CPU code just wipe them out. Ollie

I add some lines in devices.c and pci_device.c In case to disable the onboard vga to use add on card. Please check it. YH

The problem is no body touch that range. Even init_ecc_memory will skip the first 1M range.

The MTRR can direct access of this region to the main memory or to IO cards. Because the VGA card is inited before CPU, the MTRRs are not inited correctly. When BIOS loads font data, it loads it into main memory not the DRAM on the card (actually also on the mainboard). Ollie

Does linux kernel parse linuxbios table?
by Liu Tao 14 Jan '05

14 Jan '05

Hello Eric, I searched the linux kernel mail archive and found your patch for x86 boot linuxbios support, but I didn't find the linuxbios table parse code in linux-2.6.8.1, does linux kernel still parse the linuxbios table now? Regards, Liu Tao

No, Top to down will more worse. 1. I thank Northbridge PCI_DEV(0, 0x18, 0)... should be initial before CPU.... 2. In tree apic cluster is after pci_domain.....

It seems after if after cpu init do the onboard vga init, it will work. The CPU init only do the init ECC and clear that after 1M. ... Werid! And it is not wiped out after power off.

I would change dev_initalize to following void dev_initialize(void) { struct device *dev; printk_info("Initializing devices...\n"); #if CONFIG_CONSOLE_VGA == 1 for (dev = all_devices; dev; dev = dev->next) { if (dev->enabled && !dev->initialized && dev->ops && dev->ops->init) { if( dev->on_mainboard && (dev->rom_address!=0)) continue; printk_debug("%s init\n", dev_path(dev)); dev->initialized = 1; dev->ops->init(dev); } } #endif for (dev = all_devices; dev; dev = dev->next) { if (dev->enabled && !dev->initialized && dev->ops && dev->ops->init) { printk_debug("%s init\n", dev_path(dev)); dev->initialized = 1; dev->ops->init(dev); } } printk_info("Devices initialized\n"); } -----Original Message----- From: YhLu Sent: Thursday, January 13, 2005 6:51 PM To: Li-Ta Lo Cc: Sagiv Yefet; LinuxBIOS Subject: RE: Running with VGA It seems after if after cpu init do the onboard vga init, it will work.
