I've just spent several hours, on and off, trying to get an old PC Chips
motherboard to recognise a Socket A XP2600 (Barton) cpu, ....at least I'm
sure it is a PC Chips - it has Eagletech A30LR on the motherboard booklet, a
little white sticker on the motherboard saying v3.1 (not 3.1b), and after
lots of hunting around the web I'm convinced that it was also sold as an ECS
K7S5A and as PC Chips M830LR, and several other makes I noticed along the
way. I've reflashed it several times with hopeful *.rom binary's (it's an
AMI bios), but, this board stubbornly refuses to recognise the XP2600, and
shows XP1800 which was what was on it. Also in the CPU settings in bios -
in the multiplier setting there's a funny symbol and a number stuck beside
each other. I've had an extended character (that was used to draw double
line boxes in DOS), right next to a 4, and similar right next to an eight
etc. Really disappointing was the 020809.rom (from the PC Chips site)
which said that this bios tweak was to get the board to recognise xp2400 and
xp2600 cpu's

....any ideas anyone ? ...and if there was someone out there with an old
A30LR / M830LR / K7S5A motherboard with a Socket A XP2600 Barton cpu on it,
and which is correctly recognised in bios, and could email me the bios, of
course that would be heaven :-)

best regards, TIA

Have you tried contacting Eagletech? They built customized computers, perhaps they
can qualify what board is used.

Also the POST should have a series of numbers/letters at the bottom of the screen,
part of which is for the mobo.

Your CPU may require a 333MHz FSB before you can see its full
potential. I don't know whether your motherboard supports that.

BTW, MS groups are inappropriate for this type of question. You will
no doubt receive better support from a hardware group.

Your motherboard is limited to an FSB of 266/133 MHz.

There are two flavours of the XP2600 CPU. One supports an FSB of
333/166 MHz and is multiplier locked to 11.5x, the other supports
266/133 MHz at 15x. You may have the former, in which case it would be
operating at 133 x 11.5 = 1530MHz, which is the same spec as an
XP1800.

See http://en.wikipedia.org/wiki/List_of_AMD_Athlon_XP_microprocessors

To get your CPU operating at its rated speed, you need to unlock its
multiplier. This requires some surgery to the links on the CPU's
surface.

Thanks Brian,

....I suspect it's just coincidence that there's a "Eagletech" PC Shop, and a
batch of PC Chips motherboards branded with the same name ? ...but, I may
look into it.

Thanks Franc

Just had a quick look at the web address you posted, it looks excellent, and
I'll be having a more thorough read very soon but, am now checking and
replying to my desperate pleas ! I was aware there were two xp2600's, KV3
clocked at just over 2ghz and only 256kb L2 cache, and the KV4 Barton model
1917mhz and 512kb L2 cache (which is what I still have in this PC.)
From time to time across recent years, I keep an eye on eaby to see what
xp2600, 2800 3000 3200's are making ...usually ridiculous prices (cheaper to
build a new 64 bit PC!!) but, xp2600 prices finally started to drop, and I
told a friend to bid on one and he got it for £22. It arrived a few days
ago and it is a K74D , I fitted it ....and now I wish I'd kept my mouth
shut.
It was so long ago that I built his PC, going from memory I though he had a
M848ALU like mine but, it turned out to be Eagletech A30LR / PC Chips\ECS
M830 ...call it what you like.
The "PnP CPU" option in bios toggles fsb 100/100 133/133 and I think other
permutations of that, but, the multiplier field gets a funny symbol in it.
It is a AXDA2600DKV4D Barton, i.e. not the KV3D
....so I'll have to start REdoing my homework, ...on something that's sooooo
old !!!

I think the penny just dropped, my M848ALU mobo uses 166mhz fsb (333/ddr),
and as I siad I thought he had a M848ALU like mine, (but, it was my brother
who got the other M848ALU all those years ago!! i.e not my friend), so I
think you've hit the nail on the head "Supports 200/266 MHz Front-Side Bus"
it says in the manual !
....i.e. he's only got a 133mhz(ddr266) front side bus ! BiiiiG Oooops !

best regards, Richard
