[LinuxBIOS] Tyan Tiger 100 S1832

Hi Richard,

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.

Meager but improving ....

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

Maybe I can buy another Tiger 100 to experiment on. I'm still running 
my server 24/7 with the one I have now.
