CPU upgrade.

Ibm Aptiva, 2139-E6C, Pentium II 400 MHZ (MMX)
Motherboard : Acer V66XA (Ibm custom made)
Bios Version : V66EN2M Bios date : 10/12/98
case : ATX minitower
Power Supply : 145 Watts.
Momory : PC-100 SDRAM Dimm, 384 MB
Jumper switch : 1(OFF), 2(OFF), 3(OFF), 4(OFF), 5(OFF), 6(ON), 7(ON), 8(ON)
System board chipset : Intel 440BX
Front-side bus speed : 100 MHZ
   I like to update CPU with Pentium III or best possible upgrade.  I don't know If current version of bios will recognise PIII CPU. Please also suggest the website I can download the latest version of bios.
   I'll replaced the power supply (400 Watts) and setup 80mm fan inside the case.

Thank You,
Amit

Unfortunately, Pentium II's only go up to 450 and came in slot-1 configurations.  Pentium III's moved to the socket370 around the 600 range, and I don't think your motherboard can handle them.  There is a possibility that you can use a slotket converter, which will let you use a socket370 in a slot-1 motherboard.  I had an Abit BH6 which worked with this, but you will need to find one on the market.
Callandor,

That's not exactly true - they may slot 1 Pentium III CPUs up to 1 GHz (though finding those has gotten difficult).  But they ("Coppermine") CPUs had different voltage requirements and you needed the motherboard to have the appropriate voltage regulator.

(I'm using two 750's in one of my servers right now).
True - the 600MHz boundary marks the limit of Katmai and the changeover to a new core and voltage requirements, which the slotket will handle.  As a practical matter, any motherboard that originated with Pentium II cpus will be difficult to upgrade to the faster Pentium III's.
I guess I can buy that - I use SuperMicro BX based boards and they had a handy description of what to look for to know if it supported the faster CPUs - the boards I had all handled CPUs faster than BX.  I agree though, if you can't find out if the board's voltage regulator will or won't work for faster CPUs, I'd NOT try the faster CPUs.
I would recommend spending a little bit more and upgrading the motherboard, CPU and RAM.

A couple months ago, I purchased a bundle from TigerDirect where an Intel Celeron 3.06Ghz CPU, Intel motherboard and 512MB DDR RAM came out to under US$100 after rebates (which I actually already received!).
I would purchase a new low end machine from Dell for example.
Software now requires fast machines.

You may have a dead horse.
New cpu+mb is about $70 when on sale (celeron ~2GHz).
Also new mb's use DDR2 memory which is cheaper than DDR or SDR.
public - yes, the RAM may be cheaper - but when you start replacing motherboards, you often have to start replacing other things - power supplies, RAM, and possibly other components.  So a  CPU upgrade may be cheaper and a better bet... and maybe not.  As I pointed out to begin with, a new computer is only 400-500.
Pretty Odd, I have the Exact Same Motherboard & i had a Celeron 300A ( The Overclocking on this was mad.. )
Anyhow i went brought myself a Slot 1 ~ 370 Converter put a 1.2Ghz Chip in it set the fsb > 133mhz ( can be done via bios )
& volia away it went, so you can make the jump, its just a a little unknown if the volatge regulator will be able to take it, just gotta be lucky when attempting something like this.
& Yeah i had 400watt when i did it also
As I pointed out to begin with, a new computer is only 400-500

That may be but celeron(2GHz)+mb+ddr2(256M) is only $100
Are you serious?  You'd recommend only 256 MB of RAM?  His current system has 384.  256 is fine for NT4... "ok" for 2000, and too little for XP.  And what about the power supply you'd likely need for a P4 class board nowaday? And note the motherboard is "Acer V66XA (Ibm custom made)" - if it's custom made, you'll need a new case, at least another $50 with shipping.  And shipping costs for the other components?  You're looking at at least $200... with parts only warranties, your "old" CD ROM/writer, old graphics card, old hard drive don't make much sense to keep... when you can replace all 3 with, plus everything else and get something faster than a 2GHz celeron for $400.

You have to keep the other costs in mind, it's rarely as simple as replacing the motherboard CPU and RAM.
>Are you serious?  You'd recommend only 256 MB of RAM?
It works, although not well. For $15 more it could be 512MB.
The poster never stated his budget. Spending more money usually results in a better pc.
Old pc like that is usually a candidate for replacement.

What site do you recommend for hardware. I use Tigerdirect and Newegg.

I am about to upgrade to a motherboard that can handle a dual core in the future and I can also install 4 gigs of memory. Two gigs will take advantage of Hyper threading.
The 5 PCI slot/4x/8x Agp slot board was chosen so that I do not have to purchase new cards. Cost 69 dollars
AMD CPU at 118
One gig Mem card 132 dollars.
Also, Tigerdirect has a site that shows how to build a PC

Since I am on a tight budget, I will retrofit my pc which is a full tower

I also agree with the above comments that the client should purchase a new low end PC.
>What site do you recommend for hardware. I use Tigerdirect and Newegg.
TigerDirect is good, provantage works, outpost/fry's if on sale, pricewatch for a vendor with good price.
