Thanks for the datasheet. On my Tyan S1832 board I can report that the chip says
"PC87309-IBW/VLJ" On my system: dmesg -s 1000000 | grep PC87 gives FDC 0 is a National Semiconductor PC87306
I'm assuming that Linux is incorrectly detecting the chipset but it's close enough to the 309 that it still works.
A lot of the NS superIO's are very similar. The cases I've seen so far are just addition/subtraction of all the "special" features. Like fan control, power control stuff, special purpose gpio. The FDC between the 2 may be identical.
sides, pins will be pretty close together. Willlook similar to this: http://www.topline.tv/qfp.html
Found it... looked exactly as you described.
I can't go past 40 or it locks and there aren't any newer updates for my MB.
I assume it's a different one and not a S1832?
Yeah. It just has a 440bx chipset on it.
An additional board would be pretty much a requirement for doing thedev work. You will need some method of programming the flash chips aswell. Either a programmer/ bios savior or ZIF socket so you can dohotswap programming. --Richard A. Smith
A BIOS savior sounds like a good insurance in any case! I'll try to find a duplicate MB.
Good choice. The only thing better than a bios savior is a ROM emulator but it's lots more expensive. Make sure when you order your replacement flash that its supported by flashrom. Most are but check to make sure. You don't have to get the exact brand of flash thats in the board since the factory part may be hard to find. Only the size and speed (and supply voltage of course) needs to match.
If you have any doubts about what chips will work just post up the part number (The one _under_ the sticker) on your bios chip and we should be able to cross it for you.
