Aladdin V chipset
by Burl Nyswonger March 1, 2000

March 1, 2000

I have begun to hack on OpenBIOS and am looking to add support for x86 and the Aladdin V chipset (ie: Super Socket7, Asus P5A, etc...). If anyone else has started work on this, or plans to, it would be nice to talk. -- Burl. - To unsubscribe: send mail to majordomo(a)freiburg.linux.de with 'unsubscribe openbios' in the body of the message

I believe that this (or something similar) has been implemented on some newer Compaq servers. There are a number of workarounds in the kernel PCI code. If someone has access to one of these, an lspci -xxx output would make interesting reading. regards, -- Dave. - To unsubscribe: send mail to majordomo(a)freiburg.linux.de with 'unsubscribe openbios' in the body of the message

I'm now in linux main. I was right at trap_init then the WinDB debugger program exploded. I love it. ron - To unsubscribe: send mail to majordomo(a)freiburg.linux.de with 'unsubscribe openbios' in the body of the message

When I say "Aladdin V Chipset", I am referring OK, this brings up an interesting issue for the OpenBIOS community. At least one Socket 7 motherboard will support either alpha or pentium in the socket. So it's the same motherboard with a different processor. All startup tasks for the motherboard are pretty much the same. I had an interesting set of discussions with vendors at extreme linux last week. There's a lot of interest in linuxbios -- from Alpha motherboards too (the alpha bios'es all have sucked very badly -- dec never got it right). As things stand openbios is too pentium-specific. So I'd like to propose an idea. 1) get into protected mode early 2) get rid of as much assembly as possible there's a lot that can move to C so we change the layout a bit. It's still early in the game, we can do this. A possible layout: bios/arch/i386/{poweron.s,protected_mode.s,memory.s,motherboard.c,boot.c} bios/arch/alpha/{poweron.s,protected_mode.s,memory.s,motherboard.c,boot.c} bios/payload/{your c files here} poweron.s is the very first set of things you do on poweron -- should be a few instructions. protected_mode.s bumps you into protected mode. On the pentium this is a few instructions. memory.s turns on memory -- this is *much* easier on the pentium in protected mode. memory.s should set up a stack and jump to C code. Motherboard.c does anything that has to be done to further use the motherboard. Boot.c gunzips the payload (either a bios-compatible code or Linux or FreeBSD or whatever) and jumps to it. I'm talking to a commercial company that is going to do something like this -- they don't want much assembly long-term, so they're recrafting openbios. I don't think most people want to do assembly. If we do this, we're not just for pentiums any more. That would be wonderful! Any interest? ron - To unsubscribe: send mail to majordomo(a)freiburg.linux.de with 'unsubscribe openbios' in the body of the message

PCI enumeration?
by Brian Hurt Feb. 29, 2000

Feb. 29, 2000

Is anyone else out there working on adding PCI enumeration to OpenBIOS? Any one have any pointers to code I can theft, er, reuse? I'm looking at the function pci_scan_bus() in the linux source code (drivers/pci/pci.c), but that looks like it just reads the results of an already-enummerated PCI bus. Help would be greatly appreciated. Brian - To unsubscribe: send mail to majordomo(a)freiburg.linux.de with 'unsubscribe openbios' in the body of the message

Cool project
by Daniel Haglund Feb. 29, 2000

Hi! I just read about your project. Really cool! Ofcourse you wan't to boot linux as fast as possible. My friend David and I have spent a few hours surfing around for a BIOS able to boot FAST. We'd like to use it for the fuel injection system we're building for my car. The computer should not only control fuel delivery and ignition but also play mp3. Preferably controlled using Sony's CD-changer protocol, but that is far away. Anyway, if you BIOS is able boot linux / rtlinux fast it would be great! That's all we need. We don't want the slow code BIOS manifacturers put in for DOS and other stuff. I'll check your news page to see your progress. Keep up the good work.

wish me luck

I am now successfully gunzipping the kernel into ram. At some point this will finish (yow it's slow under the debugger I'm using!) and I'll jump to it, say in another 15 minutes :-) we'll see. The fixes I mentioned to inflate.c are essential. ron - To unsubscribe: send mail to majordomo(a)freiburg.linux.de with 'unsubscribe openbios' in the body of the message
