Help please,question concerning an older board - A7A266 and bios upgrades

[MonkeyThatBoy]

Greets,

I just flashed this board with BIOS ver.1012. Its supposed to give me
support for newer cpu's,but when I go to pick all I have to choose
from are the same 2 processor speeds why? I upgraded from ver 1006 do
I need to upgarde in steps or what?

thats the way it works. you can run the processor at either of those 2
FSB speeds (prolly 100 and 133 mhz) or in manual mode.

I see a board revision number requirement on this page:

http://www.asus.it/support/cpusupport/cpusupport.aspx

Half the processors listed there need PCB revision 1.10 or later.
Look for some white text on the surface of the motherboard, with
the rev number listed.

And all 1.03 revision owners can tell you that page is not accurate. The
clue is that even the 1.03 boards will support up to (at least) 2400+,
but it can be tricky getting the clock speed right. ASUS has stated
though that the newer CPU's will only work in auto-detect only, so it's
correct that you only get the two clock speeds, one for 100 fsb and one
for 133 fsb.

In my case however, even these auto-settings weren't right. I have the
1.03 rev four-dipswitch board, I soldered the tenth dipswitch on myself
and set it to ON. Leaving the Jen jumper in 'jumperfree' mode I was able
to select the right speed. This is a bit of a hack however, and won't
give you multipliers above 12.5. Those multipliers should only be
available through the CPU in auto-detect.

You mean like this article. What is the highest FSB you can set
on that thing ?

Yup.

on that thing ?

Dunno. I'll check later and post it.

Better late than never. FSB can be set, with 1Mhz increments, as high as
166Mhz, at which speed the PCI bus will run at 42Mhz.
