It's a Tyan S2880, and I'm using their sensors.conf:

ftp://ftp.tyan.com/software/lms/lms_s2880.tgz

Here's what sensors reports:

w83627hf-isa-0290
Adapter: ISA adapter
VCore 1: +1.54 V (min = +1.47 V, max = +1.62 V) ALARM
VCore 2: +1.54 V (min = +1.47 V, max = +1.62 V) ALARM
+3.3V: +3.33 V (min = +3.14 V, max = +3.46 V)
+5V: +4.97 V (min = +4.73 V, max = +5.24 V)
+12V: +4.56 V (min = +10.82 V, max = +13.19 V)
-12V: -2.25 V (min = -13.18 V, max = -10.88 V)
-5V: -3.94 V (min = -5.25 V, max = -4.75 V)
V5SB: +5.51 V (min = +4.73 V, max = +5.24 V)
VBat: +1.28 V (min = +2.40 V, max = +3.60 V)
fan1: 4354 RPM (min = -1 RPM, div = 2)
fan2: 3479 RPM (min = 5273 RPM, div = 2)
fan3: 0 RPM (min = 30681 RPM, div = 2)
temp1: +77ÂC (high = -128ÂC, hyst = -128ÂC) sensor = thermistor
temp2: +77.5ÂC (high = +80ÂC, hyst = +75ÂC) sensor = thermistor
temp3: +77.5ÂC (high = +80ÂC, hyst = +75ÂC) sensor = thermistor
vid: +1.550 V (VRM Version 2.4)

The temps and +/-12V readings are obviously wrong, and always have been
AFAIR. I've run the machine with 6 more 10krpm old full-height drives
than it currently has. I checked the max 5V and 12V current draw of the
drives and specced the power supply carefully when we bought it a couple
years ago, and it has lots of headroom on both of those rails.

I'll be booting 2.6.15.4 this weekend. The BIOS is indeed old, and I
see there's a newer one that came out a year ago. It'll be a while
before I can try it, I need to scare up a keyboard, video card, and
monitor, not to mention a DOS disk. You can tell why I haven't flashed
the BIOS in years...

Still, I don't see why the new kernel shouldn't be stable if 2.6.11.3
was.
