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

+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:       +77°C  (high =  -128°C, hyst =  -128°C)   sensor = thermistor           
temp2:     +77.5°C  (high =   +80°C, hyst =   +75°C)   sensor = thermistor           
temp3:     +77.5°C  (high =   +80°C, hyst =   +75°C)   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.
