Questions on BX Chipset
by Meinrad Sauter 17 Aug '03

17 Aug '03

Hi, after a short period of pain, I finally made LinuxBIOS running on my machine (Siemens Fujitsu Multitainer / i440BX Chipset). I use this device as a digital video recorder running (of course) Linux and Klaus Schmidingers famous VDR. Unfortunately there are some features I couldn't get to work until now, probably you can give me some hints: - Soft Power-Off: I used the APM-BIOS in my Original Setup for this. I understand that LinuxBIOS doesn't implement such BIOS functions. I also found a kernel patch that implements this feature for SIS-Chipsets. Is there a possibility to get that thin running on a BX board? - HD-Spindown: Same as above, simply doesnt work with my current LinuxBIOS setup - VGA: The Multitainer has an onboard MPACT2 Graphics adapter. It would be nice to have, but not really required. From the docs, I think I could make it work using ADLO or with the builtin VGA support. What do you think? - Wake on RTC: Not even the original BIOS supported this. Anyway I don't think its a hardware limitation. Do you think it is possible to implement this for LinuxBIOS? Thanks for your answers and keep up the good work! Meinrad -- Meinrad Sauter email: meinrad.sauter(a)gmx.de

EPIA-ME6000
by Leon Woestenberg 09 Aug '03

Hello, I have been fiddling with etherboot 5.0.10 and freebios(v1) from CVS today on a EPIA-ME6000 platform. This is the unit with a low speed clock (500MHz?) Eden C3 processor which copes with passive cooling. I think it is EPIA-M9000 alike otherwise. Using a hardware flash programmer, I first copied the VIA BIOS from the STT39SF040A (256Kbytes) into a STMicro 29F040B (512Kbytes) device. That only worked after I copied the BIOS into the upper half of the larger device (from 0x40000 to 0x7FFFF). So I recon the highest address line is not connected on the board and so the FlashROM sees high-impedance on its most significant address line (and addresses the upper half always)> I followed the HOWTO/EPIA document to the letter (without the VGA BIOS at first) booting linuxbios w/ via-rhine.elf payload. When booting, I merely got garbled output on the serial port. I have double checked that the config file reads 115200 and that my terminal reads 115200 8N1. (The 115200 is assembly hardcoded in the vt82c686 superio code -- does it cope with my different processor speed? I do not have the datasheet (yet?). After that, I have tried all speeds on the terminal without result. Is the EPIA-ME6000 (aka M6000) already reported to work here, or are you guys'n'gals refering to the M9000 and M10000 alone? How can I help? Regards, Leon.

K7SEM support broken in freebios?
by Thomas Wehrspann 09 Aug '03

09 Aug '03

Hello, is seems that the support for the ecs k7sem got broken. When i use the current CVS copiling is no problem, but when i boot linuxbios stops before the mtrr stuff with "Enabling cache...". I followed the procedure in the howto and used the serial console (no debug). The CVS version from 2003-04-01 works, the one from 2003-05-01 works not. Thomas

Eric, Great. Then there should be no big issue on opteron any more. Can you send to the new raminit.c to me now? Regards Yinghai Lu

Eric, Several Macro in console/console.h should be changed. For example: #define print_debug_hex8(HEX) printk_debug("0x08x", ((HEX)) #define print_debug_hex16(HEX) printk_debug("0x016x", ((HEX)) #define print_debug_hex32(HEX) printk_debug("0x032x", ((HEX)) to: #define print_debug_hex8(HEX) printk_debug("0x02x", ((HEX)) #define print_debug_hex16(HEX) printk_debug("0x04x", ((HEX)) #define print_debug_hex32(HEX) printk_debug("0x08x", ((HEX)) regards Yinghai Lu -----邮件原件----- 发件人: YhLu 发送时间: 2003年7月31日 20:44 收件人: ebiederman(a)lnxi.com 抄送: ron minnich; Stefan Reinauer; linuxbios(a)clustermatic.org 主题: 答复: Fixes for Tyan s2880 Eric, I see.

Eric, I have checked your old k8/cpufixup.c, and it already has TOM2 etc setup. and SYSCFG_TOM2_EN...etc...

There has been enough code churn that my head is still spinning in trying to get in sync with the main tree. I have updated raminit.c so that it now handles the case of each memory controller starting from 0 cleanly, and I have updated cpufixup.c so that we are handling > 4GB of memory properly. TOP_MEM2 was not getting set to the proper value. fill_last was pretty much a duplicate of route_dram_access except different assumptions were made, so I have removed fill_last again. If you have memory that doesn't get setup properly now holler. So we should be pretty close. Before I can go much farther I need a test for pre rev c0 cpus. Because a lot of the remaining memory code needs to be conditional on it. I am in the last stages of stabilizing an internal version to be used in large scale testing to search for hardware incompatibilities. I also have a the links width and speed being automatically setup properly. But the way I discover the links is still kind of nasty, so I am not quite ready to push the code back yet. I should be switching over to the new configuration system on Monday and once that is sorted out quite I can start putting hard codes where they belong in the board specific configuration. Eric

Eric, I have made two changes in raminit.c 1. csbase counting 2. fill_last to make sure kernel to scan NUMA successfully. For s2880 it can work with 4*1G+2*256M RAM, and doesn't work with 4*1G+2*512M or 4*1G+2*1G. I would try to substitute raminit.c with hardcode one to test for 6G, if it can help. Please advise.

is there any way to boot linux without etherboot?
by gimyung han 31 Jul '03

31 Jul '03

I followed you HOWTO and succeed in Linux using LinuxBIOS with VGA Is there other way to boot Linux using LinuxBIOS without etherbooting? I saw message asking whether I will choose netbooting or local on the logging message? is option to choose the way to boot system? like local boot? If so, how to do that? do I need to load whole Linux kernel on the bios rom? lik using a DoC ? is anyone who boot Linux in other way on the EPIA mainboard? Thank for any help........... _________________________________________________________________ 도처에 도사리는 재해의 위험들.
