Was a newbie, now a polliwog
by Thomas Fritz 22 Jul '04

22 Jul '04

I became interested in linuxbios a while back, and while I've subscribed to this list I've never done anything with it. I've learned quite a bit more since then, and I'm even working on reading the Linux From Scatch book. I've come back around to it again, for two reasons...I have a working laptop (IBM TP 390X), and an extra mainboard for the laptop. I have to do a password recovery on mainboard, but I was thinking if I'm going to go through the trouble, I would like to try something with it. Especially with the TSSOP flash bios chip within easy reach :) The other reason...I've been looking at embedded applications lately, and I don't really feel like going the DIY hardware route...since I have access to a surplus source of IBM thin clients (403GCX PPC, PC87303 SuperIO, S3 Trio64V+ video, single PCMCIA slot, two EDO SIMM slots, parport, serial, mouse/keybd, DP83907 ATLANTIC II ethernet, and a whopping 512KB AM29F040 flash bios), which have everything I could want, except USB, which a PCMCIA card could fix. What I want to do with one of the thin clients is put on linuxbios, and since I would be using the PCMCIA for USB, boot a compact system off of a USB memory stick. I was wondering how far along things have come, and if anyone has done something like the USB booting, or even what other devices linuxbios can boot a system off of? Also, after reading about all that's been done with the X-box project, and the mod chips they sell, I was wondering if anyone has had any thoughts on something like the Xenium X-box mod chip?

Sis 630 memory init
by zhu shi song 22 Jul '04

22 Jul '04

I have met two problems when using V1 linuxbios for winfast 6300. (1) For winfast 6300, it is not compatible with some SDRAM. (2) For ECS P6STMT board which uses sis630et chipset, IPL hangs when ipl use stack to read Linuxbios from DOC. The two problems are all related to memory init. Maybe the current memory init procedures in freebios V1 is not complete. Who know how to init SDRAM correctly, so it can work for more SDRAM and more boards? zhu --------------------------------- Do you Yahoo!? New and Improved Yahoo! Mail - 100MB free storage!

trouble with SDRAM when using sis630 SDRAM synchronous mode
by zhu shi song 21 Jul '04

21 Jul '04

(1) ECS P6stmt board use SDRAM synchronous mode. I've got P6STMT motherboard based on sis630et. It's strange that the 0x8e is equal 0 which I have read from linux running on the board, that means the board uses SDRAM synchronous mode. (2) The board halt after setting 0x8c~8f value same as bios setting. I set 0x8c~8f (in dll.inc) values to which I have read under linux. But ipl can't copy linuxbios from Doc to RAM. I have tested doc_mil.inc. When the second "call doc_reset" that is the second time to use RAM stack(%ss=$0x400, %sp=$0x0), the board halt. (3) winfast 6300 Max board use SDRAM asynchronous mode. I have read 0x8c~8f values of winfast 6300. The value of 0x8e is 0x3. So winfast6300 use SDRAM asynchronous mode. IPL can boot linuxbios and linux successfully. (4)under p6stmt Even I set register 0x50~0x5A (except 0x52 and 0x57) value to what I have read from its bios. IPL can't copy linuxbios to RAM either. Who has met the same experience? I need help. zhu --------------------------------- Do you Yahoo!? Vote for the stars of Yahoo!'s next ad campaign!

I don't mind the direct mail but please cc the list for any LB related questions and such as there is a lot of stuff that I may not know the answer to or that someeone has a better answer for. First: You need to figure out how you are going to get LB onto your motherboard. You need to figure out what type of Flash part you have and how you are going to program it. Who makes your mainboard? Are there specs (or pictures) on-line I can go look at? What kind of IC programming tools to you have access to? Second: You need to figure out what SuperIO is on your motherboard and if LB supports it. The SuperIO is going to be responsible for the serial port output. If you don't have serial output. Debugging is going to be _much_ harder. SuperIO's are usually on the ISA bus so lspci isn't much help you have to look on the board and get a Mfg and a part number. If LB dosn't support you super IO it's not hard to add but you will need the SuperIO docs.

Voodoo 3 (rev 01) This may be a problem. None of the AGP registers in the Northbridge are set. Our board has onboard PCI video. A bitworks/ims manboard config should boot to a payload easy assuming you can program the flash. Is the flash part socketed? Also lspci dosen't show what SuperIO you have. What superIO is on the board? You will have to have that setup correctly to get serial output.

RE: Pentium-M with E7501 Chipset Implementation

You may need to copy 82801ER to 82801CA, and change device id to meet that with CA. Regards YH _____ From: Jay Nelson [mailto:jay.nelson@copansys.com] Sent: Monday, July 19, 2004 2:57 PM To: linuxbios(a)clustermatic.org Subject: Pentium-M with E7501 Chipset Implementation Hello, I am so pleased to find a freebios for Linux Im beside myself. I have been researching freebios2 with the hope that I can use it for the following configuration: Intel Pentium-M (Dothan) 2MB L2 cache running at 1.8GHz Intel E7501 chipset: MCH P64H (82870P2) ICH3 (82801CA) Headless with RS232 mapped to a custom FPGA connected to the ICH3 PCI32 bus.
