Please how can I update this bios

[uesquebeathus]

Hi, guys, sorry if this is a bit heavy but I am a bit stuck for a way to resolve this problem.

I have a problem with a next door neighbors computer , it came to me not booting I eliminated everything and found the CPU an AMD Athlone 2200 was not working, I replaced it with an 800 and got the pc to work, the boy decided to purchase an AMD Athlone 2000

I have put the new processor and the graphics card fan was not working so I replaced that also, the computer works. but there is still something wrong.

I feel a Bios update could resolve the settings but I cannot get ant update tools to work,

If I set the bios to safe settings and then try to reboot, it shows cpu2000+, reboot a few times nore and it goes back to 100Mhz cpu1250 if I set the CPU Mhz at 133Mhz and the multiplier at 1.2 I get the processor to run at the 2000+ as it is supposed to, but after switching it on and off a few times the Mhz drops to the base figure 100Mhz and the multiplier drops to 1.0 the processor then runs at 1250 instead of 2000+. the processor i used to test the motherboard id an 800Mhz so it did not require a multiplier so the problem was not there to see. I cannot get the bios/cmos to remember/hold the settings, I replaced the motherboard battery and reset the bios and saved it a few dozen times but the same thing keeps happening.

I have been to the motherboard (Pcchips848Alu) makers PC-Chips web site and downloaded the latest bios update m848a16 which was the last one issued, and they no longer support the motherboard. no more updates will be supplied from then.but the motherboard chip will not allow

itself to be updated. I have tried AFUDOS, AFUWIN, AMIFLASH, bios1351, and aminf342 (PcChips own Update tool), all have failed the message is "this motherboard does not support Flash, also AFU is not supported in this Bios,

I am a bit stumped

I do not know what caused the original damage, when I saw the machine two screws fell out of the case, they might have been the cause and short circuited a bit of the motherboard. but I cannot so far resolve this fault, and.this problem is a first for me,

I really hate to be beaten by this machine.

Dumb question,but ... have you checked the "Bios Write Potect" setting in the Advanced Options of Bios ?

Hi, Ponch,

I Tried a new battery, changed the ram, the boy tells me there is no password, but the password protection is grayed out, i cannot click on it to see or adjust. its like the entry for Auto adjusting the CPU it is set at manual and I cannot change it either

it is an AMD 2000+ I have tried to bring it up from the 1250 Mhz to 1800 even 2000 but it stays at the changed setting only for a few start ups then goes back in the bios start up screen to 1250 and the bit i forgot to mention was the sdram 512 mb memory drops from 400 to 133Mhz. I have set the bios failsafe settings and restarted, it can show in the startup screen as a 2000+ again only for a few startups then it goes back to a 1250 processor in the bios start up screen

I am sorry if I seem to be repeating myself in explaining the problem

any ideas please

It could be that the BIOS slows down the bus speed when the system doesn´t start well. I think that motherboard has become bad, and I´m not surprised with that; it´s a PC-chips mobo.

I would replace the mobo and the CPU, just sell the CPU again on ebay or so and get yourself a motherboard+CPU combo that has DDR(1) support. I would not replace the Socket 462 any more, only when you can get them very cheap...

That's for preventing a BIOS flash.

Also, 133 Mhz is the correct FSB for an Athlon XP 2000+

Unless you have one of those newer Athlon XP chips that are rebadged as "Sempron". In that case, 166 Mhz probably is the correct FSB.

A BIOS flash is not an update?

A BIOS flash is not an update?

That's upgrading the BIOS to a different version, *not* changing the configuration.

Well yes, ain't it what the thread is about ? "Please how can I update the Bios ?"
