Aladdin V chipset
by Burl Nyswonger
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.

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.

any hints on what to do just to get timer interrupts going are most
welcome :-)
geez, this is getting close!

linuxbios: getting there
by Ronald G. Minnich
I'm now in linux main. I was right at trap_init then the WinDB debugger
program exploded.
I love it.

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?

PCI enumeration?
by Brian Hurt
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.

Cool project
by Daniel Haglund
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
by Ronald G. Minnich
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.
