Hi (and welcome back to PC repair 101 ;o)
I've tried the link that you provided - unfortunately there's no manual
available for download. Anyhow with regards to the BIOS settings I'll use
the manual for the Via KT400 board as it uses the Phoenix/Award BIOS.
First off the jumper issue - you don't need to use the CMOS clear jumper. To
explain before the current problem did the motherboard correctly detect an
XP3000+ CPU? If so then you don't need to worry about a jumper to set the
correct CPU Front Side Bus (FSB) it'll already be set correctly.
However if you need to set the jumper for the 3000+ look in the manual for
something like 'CPU FSB jumper' this will tell the mobo whether you're
running a 200, 266 or 333 MHz FSB CPU the 3000+ is a 333MHz FSB CPU (as far
as I'm aware). I'm afraid you're on your own when it comes to finding the
correct part of the manual to look under but it should be in the section
Hardware Installation under Jumper Settings or similar.
Now to the multiplier/FSB issue (this is in the BIOS).
Please note these instructions are from the KT400 manual (I'm just hoping
the BIOS is similar enough for these to work :o/ But read the manual
thoroughly so that you're sure which jumper.
Hit delete as the PC is booting to enter the BIOS. First look for Advanced
Chipset Features then DRAM Clock Drive Control. Under the DRAM settings
choose DRAM Clock [By SPD] and DRAM Timing [Auto By SPD]. These should take
care of the memory speed automatically. If this doesn't work then manually
choose 166 MHz (for PC2700, 333 DDR MHz memory).
If the above settings are already using SPD & Auto By SPD leave them alone
for now.
I am assuming you're using PC2700 (333 MHz DDR) memory btw.
Hopefully you're still in the BIOS screen at this point?
Next go into Frequency/Voltage control and make sure that Auto Detect
DIMM/PCI Clk is [Enabled] and CPU Clock is set to [Default]. Then hit the
F10 key to save and exit the BIOS. The PC will restart and *viola* (we both
hope!) the CPU should be detected as a 3000+. To explain the 3000+ is a
2.158 GHz CPU i.e. The default FSB is 166 MHz with a multiplier of 13 (166 x
13 = 2.158 GHz).
If you still experience problems please come back to me - hey it's much more
interesting than my day job ;o)
BTW did you manage to sort out the floppy drive issue?
Regards
BillL
XP3000+ runs with a 13x multiplier and a default front side bus speed of
166Mhz.
