VIA Northbridge's vt8601 and vt8604
by Adam Talbot 07 Dec '04

07 Dec '04

Can any one give the the difference between the VIA Northbridge's vt8601 and vt8604. Will the code from the vt8601 be able to boot the vt8604? -Adam Talbot

epia problem
by Luc Belliveau 06 Dec '04

06 Dec '04

I compiled from freebios2 from cvs, when I boot all I get back from the serial port is: LinuxBIOS-1.1.7.0Normal <date> starting.. vt8601 init starting Slot 00 is SDRAM 04000000 bytes x2 Slot 01 is empty Slot 02 is empty Slot 03 is empty vt8601 is done 0 that's it. I tried changing the DEFAULT_CONSOLE_LOGLEVEL but when I do that the resulting rom stops at Slot 00 is SDRAM 04000000 bytes x2. I can't add uses DEFAULT_CONSOLE_LOGLEVEL or option DEFAULT_CONSOLE_LOGLEVEL in the Config.lb file either, the buildtarget scripts shuns it. I'm using FILO as the payload, with no vga bios yet. Could it be a FILO problem? I've never seen linuxBIOS before yesterday so I don't know what should be appearing on the terminal.. Any assistance would be appreciated :) Luc

jump to boot code
by Gin 06 Dec '04

This is the message I got in the end. Linuxbios tries to load the ELF image. It seems that there are 2 segments in the ELF. In the end, linuxbios jumps to an entry that looks like the in the middle of the first segment. Does it look right? The FILO.elf doesn't seem to load succeffully.

Same thing, with one small difference... I turned debugging on and this is what I get : find_ide_controller: found PCI IDE controller 1106:0571 prog_if=0x8f find_ide_controller: primary channel: native PCI mode find_ide_controller: cmd_base=0x0 ctrl_base=0x0 ide_software_reset: Waiting for ide0 to become ready for reset.. ok init_drive: Testing for hda init_drive: Probing for hda Invalid IDE Configuration: 7ed8 <-- this line used to be 3ed8 with my previous conf init_drive: Testing for hda init_drive: Probing for hda print_status: IDE: status=0xa1, err=0x0 Drive 0 does not exist boot: Also the first time I compiled filo and the rom, it halted at the elfboot screen, then I recompiled with the same settings, and filo loaded.. strange..

RE: K8 D0 support

Opteron Rev D0 support done. So I need to wait for AMD put the updated Bios porting guide including Opteron Rev D0 info. Only after that, I can commit the patch? Or ask the AMD to review the code?

My impression the biggest change was the E0 stepping processors. In any event until the information goes into the public datasheet I can't publish anything. Eric

Hello, I am having trouble getting freebios2 to build for a EPIA-MII board. I cannot find any information anywhere on how to build the v2 bios for EPIA-M based boards. Can someone please explain how you do this? Thanx, Brian Abreu

Allocating Resource for Legacy VGA Buffer
by Li-Ta Lo 04 Dec '04

04 Dec '04

Eric, I tried to allocate a MEM resource for legacy VGA framebuffer (0xA0000 - 0xBFFFF) on AMDK8 NB Fun 1. I find a new mem_pair and assigned base and size of the resource as the code show in the bottom. But at the run time the resrouce allocation code still try to allocate that resource to 0xA0000 to 0x002ffffff. Why it does not care about the resource->size field nor the FIXED flag ? Ollie static void amdk8_create_vga_resource(device_t dev, unsigned nodeid) { struct resource *resource; unsigned link; for (link = 0; link < dev->links; link++) { if (dev->link[link].bridge_ctrl & PCI_BRIDGE_CTL_VGA) { printk_info("%s: bridge on link %d has VGA device\n", dev_path(dev), link); printk_info("creating MEM pair for VGA memory\n"); /* Initialize the io space constraints on the current bus */ resource = amdk8_find_mempair(dev, nodeid, link); printk_info("MEM pair register %x\n", resource->index - 0x100); resource->base = 0xa0000; resource->size = 0x20000; resource->gran = 16; resource->align = 16; resource->flags = IORESOURCE_PREFETCH | IORESOURCE_MEM | IORESOURCE_FIXED | IORESOURCE_ASSIGNED; } } } static void amdk8_set_resources(device_t dev) { unsigned nodeid, link; int i; /* Find the nodeid */ nodeid = amdk8_nodeid(dev); amdk8_create_vga_resource(dev, nodeid); /* Set each resource we have found */ for (i = 0; i < dev->resources; i++) { amdk8_set_resource(dev, &dev->resource[i], nodeid); } for(link = 0; link < dev->links; link++) { struct bus *bus; bus = &dev->link[link]; if (bus->children) { assign_resources(bus); } } }

about MAINBOARD_POWER_ON_AFTER_POWER_FAIL
by zhu shi song 04 Dec '04

04 Dec '04

I'm using i845gv based MB. The superio is w83627hf . I have set MAINBOARD_POWER_ON_AFTER_POWER_FAIL=MAINBOARD_POWER_ON.Before linux booting up, I turn off power switch, when turn on power swith again, MB can boot again. But when I have booted linux successfully, I can see the console and can login linux, at this time I turn off the power switch and after 10secs then turn on it, MB can't boot again. Who have such experience to make mainboard power on again after power fail using software solution? tks zhu __________________________________ Do you Yahoo!? Yahoo! Mail - 250MB free storage.

How I can start a cluster with M825G VIA KM266-8235,
by Edmanuel Torres 03 Dec '04

03 Dec '04

I want to build a cluster based in the M825G with chipset VIA KM266-8235 mainboard from PCCHIPS, but I have found that this is not supported by the available configuration files in the mainboards folder. I wonder is somebody can help me in to find the way to make this board work with LinuxBios?. below is the output of the -lspci -vvv command.
