As a fallback plan. If they do not permit spec release, I plan to wax eloquent to them if we succeed. May be they will get it. rgds jtd

I have 2 kobian (P4M266a and P4M266v) boards using different sound chips and one with capability to boot from s mart card (whatever that is). Inetrchanging the bios produced the additional boot capability. Everthing worked fine even under windose (which afaik uses the bios during runtime). Also buying boards might be a little easier. And in any case it would not hurt. rgds jtd

Re: Geode GX1 and IRQ tables
by ramesh bios 01 Mar '05

01 Mar '05

The URL for the Cox/Weinigel thread about PIRQ tables on the geode gx1 is at: http://lkml.org/lkml/2002/7/5/104 I'm doing a little bit more analysis of the problem now. I've been looking at the following block of code from 2.6.10's pci/irq.c. First of all, LB states this during bootup: --- Checking IRQ routing tables... /bios/freebios/src/arch/i386/lib/pirq_routing.c: 30:check_pirq_routing_table() - irq_routing_table located at: 0x00008740 done. Copying IRQ routing tables to 0xf0000...done. Verifing priq routing tables copy at 0xf0000...failed Wrote linuxbios table at: 00000500 - 00000664 checksum f9fe --- I'm not sure why the copy to 0xf0000 failed. That's kinda odd but I'll live with it for now. Now, I put some debug in the kernel code to see whether it found the pirq table and I saw: --- no pirq_table so calling pcibios_get_irq_routing_table pirq_table=00000000 --- coming from pcibios_irq_init. So based on the code appended below, I believe that the kernel isn't finding the pirq table. And I think this is because the kernel's pirq_find_routing_table function only looks from __va(0xf0000) to __va(0x100000) whereas LB puts it at 0000500. The second attempt that the kernel makes to get the PIRQ table is with pcibios_get_irq_routing_table and that fails too. I need to look at that, but first I think I'll look into why the copy to f0000 fails. In the meantime, any advice? --- static int __init pcibios_irq_init(void) { DBG("PCI: IRQ init\n"); if (pcibios_enable_irq || raw_pci_ops == NULL) return 0; dmi_check_system(pciirq_dmi_table); pirq_table = pirq_find_routing_table(); #ifdef CONFIG_PCI_BIOS if (!pirq_table && (pci_probe & PCI_BIOS_IRQ_SCAN)) { printk(KERN_WARNING "no pirq_table so calling pcibios_get\n"); pirq_table = pcibios_get_irq_routing_table(); printk(KERN_WARNING "pirq_table=%p\n",pirq_table); } #endif if (pirq_table) { printk(KERN_WARNING "had pirq_table\n"); pirq_peer_trick(); pirq_find_router(&pirq_router); if (pirq_table->exclusive_irqs) { int i; for (i=0; i<16; i++) if (!(pirq_table->exclusive_irqs & (1 << i))) pirq_penalty[i] += 100; } /* If we're using the I/O APIC, avoid using the PCI IRQ routing table */ if (io_apic_assign_pci_irqs) { printk(KERN_WARNING "using io_apic to assign irqs\n"); pirq_table = NULL; } } pcibios_enable_irq = pirq_enable_irq; pcibios_fixup_irqs(); return 0; } --- --- "Ronald G.

Re: Can any one ID this board?
by ramesh bios 01 Mar '05

01 Mar '05

Hey Adam, I think it's a typical geode gx1 board as well. I'm no expert. But here are my guesses. VGA is typically 16 pins. LPT is typically on a 26 pin header. Serial ports typically on 10 pin headers. Keyboard/Mouse typically on one 6 pin header. I think I see parallel port at the horizontal 26 pin header at the bottom right of your top pic. The horizontal header at the top left looks like a 44 pin IDE header. One thing that you could do is get the MAC address of the ethernet and that might give you an idea of who owns that block of MAC addresses. So long as it's not RealTek, of course. I don't know what the long vertical connector, my eyesight's failing me but it looks like a 50 pin header in which case it'd be a breakout connector of the kind that advantech uses. In which case you'd have to find the datasheet. --- Adam Talbot <talbotx(a)comcast.net> wrote: > Well, I have been googling this board for the last 2 > day's and have found > nothing.

VIA chips

Does anyone here happen to know if VIA works with smaller companies who want to create reference designs using thier processors and bridge chips? Or only larger motherboard manufacturers.

AMD Opteron D0 support

Any one got D0 Opteron? It seems that AMD put the D0 releated info in their BIOS porting guide (PUBLIC Version). But didn't release new revision guide about that. YH

The names (type nos) of motherboards are very region dependent and boards with same parts will have different nos depending on the region and manufacturer. Why not add the chipset partnums to the motherboard info on the Supported motherboard page. rgds jtd

I've moved the three port guides over. Antony's is really good, but sadly is for v1. The EPIA one is good for V2. ron
