Perhaps I'm confused. Shouldn't OpenBIOS be able implement the functionality of LILO? I thought that LILO existed because BIOS16 are incapable of loading anything that isn't DOS-like. Doesn't LILO look to the BIOS like DOS? In other words, when a BIOS is loading LILO, doesn't it "think" it's loading DOS? > I thought, a main topic for OpenBIOS development is full access to the > hard drives so there is no trouble with large disks, large partitions and > kernels laying somewhere on them. That sounds right. So why have a new LILO? Why not just not need LILO anymore? M

Hello, A money reward for the best logo is not really the best thing you can do I think, first because it cost you money and second it has nothing to do anymore with the GNU ideology. I think it would be nicer to give away something that has to do with this project, like a T-Shirt with the logo on it, signed by the main developers, or giving away a special edition OpenBIOS hardware. ..Anton Bossenbroek Op Thu, 3 Dec 1998, Stefan Reinauer wrote: > Hi.. > > I just finnished the OpenBIOS logo contest scripts. check out the contest > at > > http://www.freiburg.linux.de/OpenBIOS/logo/ > > It's possible to vote for the logos now.

How long is the logos admission/voting open? and... Did we ever sort out an IRC channel/net to use? If not I'll start one on CMDnet .. servers exist at irc.??.cmdnet.net where ?? is one of the following ... uk se de fi no nl .... its a small quiet net so there is rarely twits/splits Yours Matthew

Hi.. I just finnished the OpenBIOS logo contest scripts. check out the contest at http://www.freiburg.linux.de/OpenBIOS/logo/ It's possible to vote for the logos now. There are not all logos online, yet, I will put them online asap. Daniele, can you post this to the information boards? We need more logos. For that I thought about setting out a prize for the best logo. Any ideas what would be best for this? As I don't have real sponsors yet and pay this prize mostly alone, it should not be more expensive than let's say US$200 Regards, Stefan. -- Can you afford *not* to use linux?

The generic BIOS is of course the current MB BIOS's, if they take on OpenBIOS, then implementing the current Flash failsafe (which IMHO is not very well implemented), similar to the 3Com Router BIOS/Firmware(which is implemented beautifully <G>), should be made the default. 3Com router Firmware has 3 parts: Boot Loader - initialises hardware can checks for valid checksum on flash. Provides a method of re-writing boot/main code, or erasing flash - Does nothing hardware dependant, works across platform. Main Code - Takes into account Version/Revision/Chipset can do all functions of Bootloader, but provides user stuff - the real BIOS as it were.....

Re: Chipset autodetect -- pro and con

A couple of ideas to consider - single all inclusive chipset support vs. modularized chipset specific builds: 1. The bios core is relatively stable 2. Chipsets keep changing 3. CPU platforms change over time - 386, 486, ........ 4. There are usually 2 or 3 places in the code where chipset initialization is called - usually very early in the code 5. Encountered these problems in the 16 bit bios over many iterations, finally arrived at a basic structure that included a chipset module. The chipset modules required some ASM and some C and some H code. Rather than create 3 files for a chipset, I created one file to keep the chipset info in a convenient place and then extracted the ASM,C, and H info into 3 temporary files when doing the build. 6. Did this about ten years ago using MS C and MASM - primitive but it works 7. MS H2INC utility is very nice - lets one use one H definition file for both C and MASM structures so they are always in sync with each other 8. A bios build was based on a configuration file (xxx.job) that defined variables for the build for a particular configuration 9. Separating the chipsets from the core code made it easier to debug developing new chipset code and to update core code - by allowing testing to verify core code on existing platforms 10. It also made creating new chipset code easier because it is all defined in one separate file. BTW - the openbios.org domain has a temporary link to M's new pages - a bit of kludge so far - but we will work on getting this prettified and organized :-) John -----Original Message----- From: M Carling <m(a)midgard.net> To: openbios(a)elvis.informatik.uni-freiburg.de <openbios(a)elvis.informatik.uni-freiburg.de> Date: Sunday, November 29, 1998 9:13 PM Subject: Chipset autodetect -- pro and con > > >There seems to be some disagreement over the issue of whether or not >OpenBIOS should provide for possibility to compile into a single binary >support for multiple chipset types to be autodetected at run-time. > >For OpenBIOS to be successful, it needs to become more attractive to >the MB manufacturers than the alternatives.

Hello, all. It seems that it will be time soon for med to add a memory allocator to my tree. I know nothing about the implementation of those, anyone who wants to try to make something up? /Daniel --

Re: call for datasheets
by Ray Jones 27 Nov '98

27 Nov '98

Check http://www.winbond.com.tw/ (taiwan) I see various permutations of the 83C787 digits (e.g 83C877), but I do not see that part. Are you sure that your part is 83C787? You can download Winbond datasheets from that web site.. Is C787 an old ('486 days) part? My recommondation is to focus on recent chipsets first because data is more easily available and the results are most useful. -Ray
