LinuxBIOS problems with DoC
by Michel Belleau 28 Aug '03

28 Aug '03

Hi. VIA EPIA 800Mhz DIP2PLCC adapter DoC Millenium 8MB Slackware 9.0 on the HD I downloaded via CVS the latest version of Linuxbios and made my epia.config file. I can hotswap my BIOS chip with the DoC and Linux sees it when I load the modules. I can erase the chip and write whatever to it. I can build a romimage (256k) with Linuxbios but I don't have to guts yet to flash it on my original chip. *** Can I write it on the DoC? How? I don't seem to be able to build with the USE_DOC_MIL=1 option set in the config file. The make command always result in a failure, because "dd" doesn't have a valid argument for the size (it's a negative value). *** What are the values needed in the config file to prepare Linuxbios to be flashed on a DoC? I tried ROM_SIZE=838xxxx but the resulting "romimage" file is too big for the DoC. *** What are the steps to write the BIOS onto the DoC? Can I go step by step and check out what's wrong easily? Here's what I tried yesterday (by heart). modprobe doc2001 && modprobe docecc && modprobe docprobe (my DoC is found) erase /dev/mtd0 0 1024 (which erases the entire DoC, right?) dd if=docpil of=/dev/mtd0 (docipl is supposed to be at the first block, right?) dd if=docipl of=/dev/mtd0 seek=1 (docipl is at the second block too, right?) dd if=romimage.via-rhine of=/dev/mtd0 seek=2 (i TRIED by guess to put the romimage I built earlier right after the two docipl) reboot (shut off the computer beacuse it hangs at "Rebooting the system...") When I power it up, nothing comes up on my serial console, just like when I tried starting the board without a BIOS chip. What can I do to test gradually my setup? What did I did wrong? Help me out please ;-) -- Michel Belleau <michel.belleau(a)malaiwah.com>

Ron, I try to move the vgabios to freebios2 for 2880. I put the BIOS option rom to 0xfff8c000, ( the second 48k).

How about PCIBIOS? does the rom need pcibios support? if so, you need both of these modules. ron

DIP2PLCC
by Michel Belleau 26 Aug '03

26 Aug '03

Hi. Where could I find a DIP2PLCC adapter ? I'm trying to learn LinuxBIOS but I found out that the motherboard I'm trying to get running (VIA Epia 800 fanless) has a socketed PLCC chip. I checked out on the M-Systems web site and they just have DIP32 packages of DoChips (Millenium). These should be compatible 1:1 with the PLCC version, right? All I need is an adapter right? -- Michel Belleau <michel.belleau(a)malaiwah.com>

Linuxbios: Booting linux from flash IDE drive on epia boards?
by Hubert Denkmair 25 Aug '03

25 Aug '03

Hello, (second try) I'm planning to build my own car mp3 player on a PC basis and now found out that the VIA epia boards seem to be supported by linuxbios. I'd love to boot my mp3 player via linuxbios to get the music playing asap... unfortunatly the linuxbios-docs are not very userfriendly - I understand that it's possible to boot the epia boards via etherboot, but can i also load a kernel from IDE devices, e.g. a compact flash card mounted into a IDE compact flash drive? If not - is there any other way to load a linux-kernel really FAST in a EPIA standalone (car-) system? Would you recommand a special board, such as the EPIA-V8000, or are they all working well? Thanks a lot for your help, Hubert --- hubert(a)denkmair.de

compatible flash chips
by Nathanael Noblet 25 Aug '03

25 Aug '03

Hello, I just received my EPIA 800 and am itching to get it up and running with freebios. I have flash parts for a board I was previously working on. I'd like to know if they are compatible, they are the same form factor (as in PLCC chips). The one in the board is a SST 39sf020a, and I have Winbond w29c020cp90b. How do I know if they are compatible? I'd rather not flash this and it not work, and then not be able to do anything with it... -- Nathanael Noblet Gnat Solutions 4604 Monterey Ave NW Calgary, AB T3B 5K4 T/F 403.288.5360 C 403.809.5368 http://www.gnat.ca/

linuxbios on arbor emcore i612?
by Hubert Denkmair 25 Aug '03

25 Aug '03

Hello list, i am planning to build my own car mp3 player in the near future. Therefore I'm going to buy a 3.5" Single Board Computer, and OF COURSE linux will be my operating system of choice :-) Since a fast boot process will be important for me, it seems very useful to buy a board supporting linuxbios. Currently I have a rather cheap SBC on my mind, the "EmCORE-i612VL", manufactured by arbor. Datasheet: ftp://ftp.arbor.com.tw/pub/datasheets/miniboards/emcore-i612.pdf Is this board supported by linuxbios? I looked at the status page and did not find information about this board or even the used i815 chipset. Are the boards mentioned on the status page really the only ones with linuxbios support? If so, can you recommand me a cheap SBC with similar features (+5V power supply only, Celeron400 or equivalent CPU, CF Socket)? Thank you in advance, seems to me you're doing great work! Hubert

Question about Opteron UnitID register
by David Hendricks 25 Aug '03

25 Aug '03

I know you guys aren't AMD tech support, I was hoping someone could help me figure this problem out. In section 3.3.8 (page 35) of their BIOS and Kernel developers guide ( http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/260… ), they have a 32-bit UnitID register. The example given lists the lowest four bits as follows: 3-2: CPU1 Unit ID 1-2: CPU0 Unit ID Ok, so you could give CPU1, CPU2, and CPU3 a unique ID with two binary digits, but I thought we were supposed to be able to have eight (or more?) CPUs? Is there something obvious I'm missing? Is the CPU Unit ID the same as the NodeID, or different? Do these CPU Unit IDs even have to be unique for each CPU? I was thinking perhaps the CPU1 Unit ID is used only by a noncoherant device attached via Hypertransport link to what it thinks is CPU1 to differentiate the CPU it's attached to from CPU0. If this is true, is it necessary since the bootstrap processor, CPU0, is the only one with access to its northbridge and memory controller at this point? Sorry if all this is complete and utter nonsense, I'm just a very curious newbie.
