Hi. I have a Aptiva 2153-E2U with 256MB pc100 RAM 128x2, on IBM's OEM
version of the Acer v70ma-95 motherboard with BIOS dated, v3.2 V70EN5H
10/10/98. The original processor was a AMD K6-2 333Mhz at 95x3.5 at
2.2v.

I recently accquired a AMD K6-2 533Mhz/AFX with a good 600Mhz rated
heatsink/fan and have switched processors. I have managed to get it to
run at 476Mhz {I left the CORE voltage at 2.2v(SW2 B4-B8), changed the
multiplier from 3.5 to 5.0(SW2 B1-B3), and increased the FSB from 95 to
100(SW3 B2-B3). Also I am currenty running under Windows XP.

These are the settings I am using now as I mentioned above; according
to the "IBM System board Layout" print out:

__________________________________________________ ___________
BUS Freq | Multiplier | Voltage | M1542 BUS Freq |
CPU,AGP,PCI | | | |
F F F | F N N| F F F N F | N N |
F=Off N=On |
__________________________________________________ ___________|

I have tried a 5.5 multiplier also but the computer only ran for a
while, and if I didn't get a error with explorer then it rebooted on
it's own, and continued rebooting once the IBM Logo vanished.

I not really sure about SW1 I tried setting that to
{(N F F)CPU-100, AGP-66, PCI-33} also with 5.5 and 5.0 but it kept on
freezing or rebooting once the IBM logo vanished.

Also I googled my BIOS and found out that there is a newer version
V70EN5H dated 10/22/98, and since the IBM website no longer supports
older systems I hoping someone has a copy of it.

Thanks.

I TOO HAVE A IBM APTIVA 2153. RUNNING WIN XP. IM SURE A BIOS UPGRADE WILL HELP, SO FAR ANY EFFORTS, BY ME, TO ACCOMPLISH THIS, HAVE BEEN UNSU THANK YOU SINCERLYCCESFUL. I'VE BEEN TOLD THAT I NEED TO FORMANT FLOPPY THAT IS TO CONTAIN BIOS UPDATE, MUST BE FORMATTED IN WIN98. THIS ALMOST NEArly IMPOSSIBLE. I DO NOT HAVE A RUNNING WIN98 OPERATING SYSTEM OR ACCESS TO ONE. ANY HELP ? ANYONE? THANK YOU IN ADVANCE SINCERLY, JOHN

John,

Are you just looking for a formatted floppy disk from a Win98 system?
If so, I still have a 98 system and could format a disk for you.
