[OT] Freebios

I don't know if anyone here is interested in this, but some time ago (1998) I started writing a pc-compatible bios for fun, but never finished it. So in case someone is interested in the little code I wrote you may find it at http://ranmachan.dyndns.org/~ranma/freebios-0.0.1.tar.gz (~67KB) ... [As long as my system is up, which should be nearly 24hours/day, and my internet connection and the dyndns.org dns updates are working...] I stopped because I had trouble figuring out how to enable SDRAM on my Pentium Mobo with Intel chipset... However for an older 486 Chipset there were specs in an old c't magazine, so I was able to boot into dos with this piece of code... (Don't know if it's still working, I did not try it recently... The floppy code is buggy IIRC... No HD support) Of course this probably doesn't help a bit with openbios development, but maybe someone will find it interesting to look at :-) GPL license, no reverse engineering of propriatary BIOSes was involved, I had to go with only a few books (Basically "PC Hardwarebook" and "PC Programmers Guide to low level Functions and Interrupts") -- Tobias PGP-Key: 0x9AC7E0BC - To unsubscribe: send mail to majordomo(a)freiburg.linux.de with 'unsubscribe openbios' in the body of the message

I have seen reports that both Intel and IBM are working on chipsets that will support that. I think the reports were talking many way SMP but possibly that is because where Itanium is positioned. This looks like it may be in the McKinley time frame. I have a strange hunch that McKinley will be bus compatible with the P4. This is what I am picking up through osmosis reading the reviews.

RE: [OpenBIOS] New power-up graphics BIOS.

SVGA may be standard, but which chip-set are you using ? The system setup can be highly unique for each CPU (PII, PIII, Celeron, Ultra-Low Power, etc), "co-processor" (440BX, 440TX, et. al.) and/or Super I/O.... These devices must be initialized before DRAM, PCI bus, etc will get started, even before the Video driver is loaded. Interested observer.... Ralph > ---------- > From: Gavin R.

Then you could be certain the chipset worked before on x86 before trying to reverse engineer the cpu initialization for the Itanium... That isn't a very aggressive plan but unless we start moving in a hurry it is probably a very workable one.

Re: sorry, it works, K7SEM (fwd)
by Ronald G Minnich Aug. 29, 2001

Aug. 29, 2001

Just a sample of what can happen. The K7SEM has two ethernet chips on it, both will probe fine. But if you try to really use the build-in sis900 chip, it hangs the board, because there is no PHY installed. So you really need a bios built for that specific motherboard. PC hardware is really just horrible. There ought to be a spec for reading vendor/mainboard ID. But the vendors change it so often that I doubt that would ever really work. ron ---------- Forwarded message ---------- Date: Wed, 29 Aug 2001 09:07:09 +0800 From: Ollie Lho <ollie(a)sis.com.tw> To: Nikolai Vladychevski <niko(a)isl.net.mx> Cc: Ronald G Minnich <rminnich(a)lanl.gov>, linuxbios(a)lanl.gov Subject: Re: sorry, it works, K7SEM Nikolai Vladychevski wrote: > > Ronald G Minnich writes: > > > please send us your kernel output.

Do not include the SiS 900 driver for any 730 board which does not have PHY with it. Those boards with RTL 8139 as LAN device are in this category. The driver will hang the machine in probing PHY.

Serial console admin is not our idea of a good time. Completely agree - the serial console is only handy when you have no ethernet. We've recently moved a 16 node cluster, which caused a couple of harddrives to give up - the serial consoles came in quite handy. regards, Per Jessen regards, Per Jessen, Principal Engineer, ENIDAN Technologies Ltd http://www.enidan.com - home of the J1 serial console. ---------------------------------------------------------- Please note: This message is intended for the use of the individual to whom it is addressed and may contain information which is privileged, confidential and exempt from disclosure under applicable law.

Well I wouldn't call it slow. I'd say someone has achieved a reasonable BIOS boot time with a stock BIOS.
