hiho... what about creating a faq ? when i told people about the openbios project they had many questions. -how can i write the bios in C ? are there libs, which are used, etc.pp.... -do you know, when u are finished with the first working bios ?.... blabla... i would maintain the FAQ, but i think that somebody has to mail me questions and answers...or just questions..so that i can ask here at the mailinglist or that i can ask Stefan directly ;). is there somone against this idea ? cya, daniele .oO http://realcosmo.hat.gelitten.org realcosmo(a)hat.gelitten.bei.infra.de Oo.

Well, I also thought about this, but I would even go as far as to build a VGA card "simulator", which would be a real VGA card, but with some kind of magic logic that would allow to read the video ram over the net. For the EPROM simulator: It will cost about 450,- DEM (~ $290) to build, according to a friend of mine who has enough electronics skills (for I have not... :-) ). If everything works out, the simulator will be ready in about two weeks' time. :-) > Should we go the way linux goes and write our own drivers or should we try > to use other bioses (i.e. scsi bios on host adapter) for that? Well, write a own driver, but support BIOS extensions as well. This way the new hardware at least works until there is a OpenBIOS driver for it. CU Simon

I'm a professional UNIX sysadmin, consulting for investment banks in NY and London. I'm excited about OpenBIOS, and this seems to be a good opportunity for me to contribute. I can donate a 486 running Linux, and the time to administer it. And a friend has just agreed to host it on his underutilized T1 in Silicon Valley. I should be able to get it up within a week.

Dear OpenBIOS readers, here's the answer from openbios.org. I'd say this is really fine :) Stefan.... ---------- Forwarded message ---------- Date: Sat, 21 Nov 1998 12:34:52 -0600 From: John Foster <john(a)tsf.net> To: Stefan Reinauer <stepan(a)wesley.informatik.uni-freiburg.de> Subject: Re: OpenBIOS Project. Stefan, A little history on myself: I began writing bios' for clone PC's about 15 years ago as a consultant. Since I had been involved in embedded and process control systems for years, these were aimed at low-volume desktop and embedded applications which usually required a lot of flexibility. About 10 years ago, I created the XT BiosKit book, which included source code in C for an embedded bios. Later that year I wrote the AT BiosKit. The books were priced at $99 and $199 respectively, which was inrtended to allow small embedded developers to create their own bios. A per-unit production fee was also stipulated. I moved from San Diego back to the Midwest in 1991 and got involved in building an ISP business and that has taken most of my time since. We soon found that our Windows NT platforms (which worked well as bios development platforms) did not solve the typical ISP problems and we tried RedHat Linux a few years ago. Obviously this awakened us to two things! - Linux is the wave of the future and that the Open Source idea that we had with our original BiosKits was really relevant. I had also written some real-time operating systems for micro and mini computers back about 30 years ago and always had intended to pursue this area just because of the enjoyment of doing it. There are two basic bios needs - support for 16-bit versions to support the traditional functionality of a bios, and a clean approach to 32-bit versions to support Linux (and similar operating systems). My previous 16-bit version is based on using Microsoft 1.52 compiler and MASM - I really want to find suitable public domain tools to update this - make it a total package by being able to include the toolset (like we have in the 32 bit world). A new 32 bit version can use GCC and NASM so with tool support readily available, the next fascinating question is architecture - which your group is addressing. So much to do, so little time......... With the Open Source movement gaining speed, I see that companies like RedHat and SendMail are able to produce income by providing convenience, support, packaging, etc., by building on an open source structure. In order to return to my spending full time creating software, I am attempting to figure out how to combine Openness with Income. A thorny question!! I hope a solution can be found. Additionally, the Open approach seems to provide an exciting opportunity to create a new reat-time system aimed at embedded applications. I have a lot of ideas based on doing and thinking about this for the last 30 years. Regarding the OpenBios.org domain, I registered this really to protect it, I intend for this to preserve the intent of opennesss and want it to be available not only for myself, but for anyone interested in this idea. So I invite you and your group to use this domain. It presently is hosted on an NT server, but forgive us, we are still learning Linux, Apache and all the rest! - our intention is to move this as well as all our other websites to Apache. If there is interest in someone in the group becoming a webmaster and site maintainer - I heartily invite hearing from you. It is good to hear from you and I invite you to convey this info to the others in the group... Best Regards to all, John O.

Yep, but have you tried to program without working RAM? No stack, only 8 registers to keep stuff in? - Believe me the first thing you wanna do is get at least the first 1MB of RAM working... > I've talked with this about many people and having support for more than > one intel chipset in one, for example, would be a knockout fact for award > bios in large compuyter pools. And there are MB specific issues such as how the SIMM/DIMM sockets are wired, how the AUX chip-select signals found on most super I/O and South Bridges are used, how the super I/O is implemented, which way to ROM is mapped after reset (do we look at the top 64k or the bottom in a 128k ROM). So I'll tell you - a BIOS image is not only chip set specific, but it is mother board specific. It might be possible to make a BIOS which works for several configurations, but that will not be as simple as putting support for several SCSI HA's or NIC's in a Unix/Linux kernel. /Daniel --

I think it should be GPL, no sane person should consider the chip set registers or motherboard interconnect trade secrets.

This is especially nice for > people with large computer pools (like admins of universitiy pools) I'd say it is hard to probe the PCI bus before you're up and running (DRAM working at least) and to come up and run you need to know which chip set you're on... Besides in addition to what chip set and which super I/O chip that is attached you might need to know hove some things are wired on the mother board. > 4) There have been many new wishes on the wishlist today, please check > them out at > http://www.freiburg.linux.de/OpenBIOS/wishlist/ > and *DO* comment on them. I have my own agenda quite clear...

openbios.org
by Stefan Reinauer Nov. 21, 1998

Nov. 21, 1998

Dear OpenBIOS readers, well, I tried to register the domain openbios.org two days ago and I noticed that this domain is already registered to someone else. As there's no contact email neither on www.openbios.org nor on www.openbios.com, I registered using the registration form on the openbios.org webpage. It seems to me that the "other" openbios project, which is registered since august 1998, is semi-commercial. Does anyone know anything about it? I will try to email the postmaster(a)openbios.org now to find out more about the other project. Just my 2 cents.. Stefan.

Some Ideas
by Wim Crols Nov. 21, 1998

Nov. 21, 1998

Hi, I recently found out about this project OpenBIOS. I was also thinking of making a better BIOS for quite some time. But haven't started yet to code anything or look for documentation. But I did think about how such a state of the art BIOS should work. Here are my ideas (any comments are welcome): - Everything which is on the motherboard and needs to set up at boat-time has to be done by the bios. - the bios also has 'drivers' for on board chips (like serial, parallel, perhaps sound and video if they are on the motherboard). - bios on the motherboard should not have drivers for extension-cards (like SCSI, video, sound, network, ...) So don't put every possible driver in the bios because it would grow to big on the long term. - bios should detect such extension cards and load the bioses on those cards (as long as it's not possible to alter bios's on extension cards the OS-kernel should load drivers for it). - bios also needs an OS-Loader so you can choose at boot time which OS you want to boot. - there should be a good API which makes it possible fo an OS to use the bios 'drivers' (whatever system or OS you have) instead of having drivers for every possible extension card. (Which means a generic SCSI-API, generic NIC-API, generic Sound-API, generic Video-API, ...) If this API is well-designed it should be possible to write kernels without one line of assembler code in it (so it would be easy to port to another architecture with a bios with the same API). This is basically what's in my mind. Please do comment about it.
