Re: linuxbios on geode gx1.....

> my config looks as follows: >----- >target pcm-5823 >mainboard advantech/pcm-5823 Ah. Cool you are using V1 that will make things easier. I can't mess with this untill this weekend but I'll certainly give it a whirl. I was wanting to try and get linuxbios up on my reference platform anyway. One question though does your board have SDRAM or DDR? My reference boad has DDR soldered on the mainboard but looking at the raminit.inc code its not obvious if its for sdram or DDR. I've got the gx1533 reference board made by Via not by NSC. Dunno if they did anything differnt. -- Richard A. Smith

Is 440BX ported to Linuxbios v2?
by Svante Signell 14 Jan '05

14 Jan '05

Hello, I have been communicating with the Linuxbios mailing list on and off (mostly off lately). I'm interested to try out the linuxBIOS on my old dual CPU board MSI-6120. The current MSI/AMI BIOS V2.0 does not support newer CPUs than Coppermine. Currently I have two old PII processors (Mendocino) installed and would like to upgrade to one Celeron 2 or dual PIIIs (Tualatin) using one or two SLOT-T slot 1 to socket 370 adapters. A 1.3GHz Celeron 2 boots with this new CPU but runs _extremely_ slow, at aronund 8MHz compared to expected 1.3GHz. This has been reported before in the thread 'Level 2 cache activation code' in late 2003. Where can I purchase a replacement BIOS chip? Placed in a socket on the main board is a 2x16 pin DIL labeled: 686 AMI BIOS 1995 CS 92222. lspci shows: 0000:00:00.0 Host bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 03) 0000:00:01.0 PCI bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge (rev 03) 0000:00:07.0 ISA bridge: Intel Corp. 82371AB/EB/MB PIIX4 ISA (rev 02) 0000:00:07.1 IDE interface: Intel Corp. 82371AB/EB/MB PIIX4 IDE (rev 01) 0000:00:07.2 USB Controller: Intel Corp. 82371AB/EB/MB PIIX4 USB (rev 01) 0000:00:07.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 02) 0000:00:0f.0 Ethernet controller: 3Com Corporation 3c905B 100BaseTX [Cyclone] (rev 30) 0000:00:10.0 Multimedia audio controller: Creative Labs SB Live!

I check the amd_early_mtrr.c with old amd earymtrr.inc. It seems the only difference is not enable SYSCFG_MSR_MtrrFixDramModEn before clear MTRR fixed. I enable that, but the result shows no change.... YH

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

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
