I still have a lot to learn, but the idea of a speedy boot process
appeals to me.
The problem is the motherboard manual doesn't really tell me
exactly which chip(s) the "National 309 Super IO chipset" is or
where it's located on the board.
The manual does refer to LM75 and LM79 chips which I believe
are temperature sensors. I can read them via the lm-sensors package.
For some reason the LM79 sensor was put beside PCI slot #5.
Oops, looks like it's actually a "lm79-isa-0290" and it's reporting a
nice cool 24 degrees C. I don't have any ISA cards anyways :)
ChipDocs has datasheets for the pc87309 and it's described as
"Super I/O Plug and Play Compatible Chip in Compact 100-Pin
VLJ Packaging" but I have to subscribe to download the datasheets.
Checking on tyan.com
I can see that Tyan does test it's boards to
work with Redhat and SUSE and I must say the old Tiger 100 board
has worked great on my Linux server. It would be really nice if
some manufacture shipped boards with Linux BIOS on them... I
wonder if anyone actually does that.

How are your hacking skills?
Meager but improving ....
LinuxBIOS V1:Supports the 440BX but it dosen't
know anything about SMP or
AGP andyou would probally need ADLO to make the video bios work.By 309 I'm
guessing that the pc87309Oo superIO? V1 seems to have reallybasic support
for enableing that on boot but the comments say itsspecific to a particular
mainbord. So some work is needed there aswell. LinuxBIOS V2I have a set of
patches vs an old version of V2 that add the frameworkfor 440BX and was
enough to make our product come up and say stuff outof the serial port.
(pc87351) However I got stopped trying to readthe RAM info via the SMbus.
For some reason I always got back zeros(or FF's I dont' remember).
Unfortunatly that product never made itbeyond prototype and so I didn't
continue to try and transition fromV1 to V2. If you are interested in
working on it I can fixup my patches againstthe latest SVN tree and submit
them. There's a lot of coding workthat still needs to be done after that
though. I have somewhat of an interest in this as I have a Dual P3
machinewith a 440 chipset on it that can't use newer larger hardrives
becausethe BIOS chokes and I also have some of the prototypes from
ourproduct that could be used for something
A couple of years back I flashed the BIOS so I haven't had any
problems with big hard drives on the Tiger 100. My server runs a
20 gig and a 40 gig.
If you want to upload your patches I'll keep plugging away at it although
perhaps there are already cheap Tyan boards on ebay that are well supported
I just don't have a lot
oftime to allocate to this. But I could test things in the evenings
andweekends. It would be really nice to have full V2 support for the 440
family. There are tons of old cheap mainboards with these chips on them
andwould be great for hobbiest or personal type stuff. --Richard A. Smith
Maybe I can buy another Tiger 100 to experiment on. I'm still running
my server 24/7 with the one I have now.
