IPMI support in Linux
by Andrew Ip March 26, 2003

March 26, 2003

Does anyone know if IPMI works under LinuxBIOS? AFAIK, there is a Linux driver patch but dunno if it still works under LinuxBIOS. -Andrew -- Andrew Ip Email: aip(a)cwlinux.com Tel: (852) 2542 2046 Fax: (852) 2542 2036 Mobile: (852) 9201 9866 Cwlinux Limited Unit 202B 2/F Lai Cheong Factory Building, 479-479A Castle Peak Road, Lai Chi Kok, Kowloon, Hong Kong.

kernel image size
by John Allen Dec. 16, 2002

Dec. 16, 2002

I need to get the kernel that I am building for my Geode sc1200 (including the linuxbios code) small enough to fit on a 256K eeprom. Is this possible? My first attempt resulted in vmlinux of 626K. After compiling linuxBIOS it gave my a rominage of 448K. Am I missing something? I tried to strip as much out of the kernel as possible. John

National Semiconductor Geode GX1 ?
by Rob van Nieuwkerk Dec. 1, 2002

Dec. 1, 2002

Hi All, I am using a small (4"x6") SBC board with a NS Geode GX1 and CS5530 for a project. It's a complete PC on a 3.5" formfactor (300 MHz Geode, SODIMM, floppy, IDE, CF, serial, Ethernet, USB, keyboard, mouse, Video, LCD, PC/104). See: http://www.axiomtek.com/product-info.php?cat=Embedded+PCs&model=SBC84510VEE… And I'm very interested in using linuxbios with this board (or a similar board: there are several manufacturers making small boards like this). I searched the linuxbios mailing-list archives for messages about Geode systems, but I only found references about SC1200 and SC2200 systems. And I did't find info on the Geode GX1 in the linuxbios status list. So my question is: - anybody know something about the possibility of running linuxbios on a NS Geode GX1 ? greetings, Rob van Nieuwkerk

Question regarding instructions...
by Nathanael Noblet Nov. 29, 2002

Nov. 29, 2002

Hello, I've gone over the instructions included on the website for the sis 630. I have a few questions on how I can do this if I am not using a sis 630 winfast mobo. I have a SBC sis530 based machine. I realize that this board is not supported but I also have the datasheet and don't mind the work that would be involved in adding support. Before I start on that though here are my question. It talks about replacing the bios chip with a DoC. I've looked at this board and what seems to me to be the bios chip is not the same shape as a DoC it is an AWARD and it is square. There is a DoC on the machine and it is rectangular. So there is no way to replace one with the other. Does that make this impossible? Or is it possible to flash the AWARD BIOS with the linuxbios code? Or, and I highly doubt this, since there is a DoC on the board can I simply remove the BIOS chip... Any suggestions? -- 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/ -- 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/ -- 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/ -- 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/ -- 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/

file system error
by Munjun Kang Nov. 29, 2002

Nov. 29, 2002

Dear linuxbios. Hello. I've worked for development of Embedded linux project in my corp. Following is decription of my projcet. CPU : VIA C3 800Mhz (EBGA) Reference Board : VT6015 Northbridge : VT8606 (include S3 twister video core) Southbridge : VT8231 (include VIA rhine II LAN core) Bootbios : Linuxbios OS : linux 2.4.19 ( ramdisk include glibc 2.3.1, busybox 0.60.5 and tinylogin 1.2 ) Now, It works well except hard disk. I try to boot the kernel in two way. First, it loads compressed kernel and ramdisk image via network using tftp protocol. Second, it loads elfImage, generated by 'mkelfImage' via network. All of them work great. (It means that I can see the prompt '\ '.) But, when I try to make a file system the harddisk, 'segmentation fault' occurs. mke2fs and mkreiserfs have same problem. For find out the cause, I try to make a file system in various method. 1. Buildin Bios + Redhat 8.0 installed harddisk + test harddisk 2. Linuxbios + Redhat 8.0 installed harddisk + test harddisk 3. Linuxbios + Kernel(newly compiled), own ramdisk + test harddisk After boot, I try to make a file system on test harddisk. In case 1, It works well. Of course, it must be. In case 2 and 3, I meet the segmentation fault. So, I think that this problem caused in Linuxbios. Maybe, this problem caused by harddisk initialization in linuxbios. But, there are no harddisk initialization code in linuxbios. Cound you help me? Thanks for reading. Regards, malas PS. In addition, memtest86 v3.0 works well without error.

Geode Kernel Config
by Adam Bezanson Nov. 27, 2002

Nov. 27, 2002

Hi, I've got an Eval card from National Semi that contains the SC1200. I'd like to try LinuxBios on it. I've downloaded both the 2.4.18 and 2.4.19 kernels to start with. What patches do I need to apply to the kernel? Is there a config file I can use to configure the kernel, or should I do it manually? Thanks, Adam

1) win xp runs under bochs now that means that it probably won't be much harder to get it to run under real hardware.. 2) net bsd if anyone feels adventurous they are welcome to test out NetBSD. If will either fully work just like OpenBSD does, or it will boot like FreeBSD all the way to exec('/sbin/init'); and then slow down to crawl. it simply has not been tested so far. the same goes for hurd. i don't think i'll have time look into either of those soon. -- Adam Sulmicki http://www.eax.com The Supreme Headquarters of the 32 bit registers
