Dear Sirs, I have been trying to use linuxbios with X on a pcchips M810 motherboard, but I could only get it to work using the fbdev driver (which lacks the speed I need). When I try to use the sis driver the screen gets black and the computer hangs. any help?

[COMMIT] baremetal toolkit
by steven james 12 Nov '02

12 Nov '02

Greetings, I have committed the baremetal toolkit to CVS in util/baremetal It is library, headers, Makefiles and linker script for building LinuxBIOS payloads. It includes two examples, hello (simple hello world) and bootselect which finds tagged ELF images in rom and allows the user to select one to boot. It is mostly built from LinuxBIOS source with bits borrowed from Etherboot.

Tekram S381-ML w/ i810
by Adam Hunt 12 Nov '02

12 Nov '02

I have a Tekram S381-ML motherboard (http://www.tekram.com/hot_products.asp?Product=S381-M) with a i810 chipset on it. In one corner there is what I belive to be the flash part. It is a socketed chip labled N82802AB. I belive it is only 512KB. Is there any chance that I could throw a larger part in there? --adam -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ NEU: Mit GMX ins Internet. Rund um die Uhr für 1 ct/ Min. surfen!

[COMMIT] fixes for linuxbios_c.ld,vt8601,vt8231,serial post and epia
by Andrew Ip 11 Nov '02

11 Nov '02

Thanks to Kevin Hester for the patch arch/i386/include/arch/intel.h lib/subr.c - fixed postcode to serial console northbridge/via/vt8601/raminit.inc - used value from Kevin Hester's reference board to stabilize sdram init config/linuxbios_c.ld - There was a serious problem in the ldsetup scripts. If the BIOS contained an odd length rodata, LD would make a bad stripped file. The objcopy tool deals poorly with sections that are not longword aligned. This resulted in the BIOS almost working, but it would be referencing the wrong offsets for some key data. superio/via/vt8231/setup_ethernet.inc mainboard/via/epia/Config - enable ethernet before spci enum in order to get mem and io space assigned mainboard/via/epia/mainboard.c - added pci_routing_fixup superio/via/vt8231/superio.c - updated to pci direct interface -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.

Help: Building LinuxBIOS for VIA EPIA
by Andy Mercier 10 Nov '02

10 Nov '02

I have a CVS snapshot that I've decompressed. It has the latest changes from Andrew Ip but I don't see any changes in it from Kevin Hester who, on 10/29, said he had some patches. I've been lurking in the email list for some time and see that Andrew Ip and Kevin Hester have made progress with the VIA EPIA. This would be my first build with what they have; so, I'm a newbie to CVS and LinuxBIOS. I'm fairly knowledgable about Linux and some revision control systems that run on other operating systems (PVCS, RCS). Although CVS is recommended for getting the files, I would hope that the snapshot can be workable but I don't know how. Currently, I don't have a CVS client running so, if possible, I'd like to have a way to use the snapshot. I'm trying to get this built but there are no instructions for the VIA EPIA board. So, I decided to look at the HOWTO for K7SEM. It says that the kernel is supposed to be patched. I don't see a VIA EPIA patch for the kernel, is there supposed to be one? I'm looking to use either kernel 2.4.18 or 2.4.19 but to match other progress with VIA EPIA I'll use what ever kernel I'm supposed to. I want to just get caught up to Andrew Ip's last issue - IRQ table.. Is there some LinuxBIOS file I need to read that I haven't yet? The CVS snapshot decompressed has resulted files with ",v" and suspect there's some other step that I may have missed to get these files with the correct filenames for make? Thanks in advance. Andy

RE: EPIA DOC - Via wont give out info..
by David Barr 10 Nov '02

10 Nov '02

FWIW: EMJ America Inc. ( http://www.emjembedded.com ) has told me that they will have the new M-Systems MD-2802-D08 DiskOnChip "Millenium Module", 8MB available in mid-November for $23 USD / ea. It's supposed to be the "same" as the M-Systems MD-2800-D08 DiskOnChip "Millenium", 8MB. Whether or not that is an accurate statement remains to be seen. I can't order a 2800 anywhere, to compare. -dBarr. >All my efforts to find out anything from via about the DOC option on >their >EPIA Motherboards has gone in veign.

RFC IDE write
by steven james 10 Nov '02

10 Nov '02

Greetings, I'm in some final testing for the first cut of the baremetal toolkit for LinuxBIOS, and have come to a decision point. In one of my applications, I need to write to the IDE drive from firmware. It was easy enough to add that to the polling driver in LinuxBIOS. The toolkit uses the same source as LinuxBIOS itself whenever possible. The question: Is it desirable to have write capability in LinuxBIOS. Since being able to write introduces new danger, should it be turned on only by setting an option? As for the toolkit itself, it is about ready to commit. It is a self contained small directory tree with it's own makefile. Any preferences on where it goes in the LinuxBIOS tree? util/baremetal?
