Hello. I have a AMI (American Megatrend) motherboard AMI BIOS, AMI 486 dx/33 CPU, 256K cache and 32 MB RAM. I need to upgrade my 255 MB hard drive since I only has 2 connectors on the motherboard. I am running Windows95, NIC card and highspeed Shaw cable internet on it. It is slowish but I manage. I bought a 540 MB conners IDE drive and 840 MB also conners off ebay which I would try to swap my present 255 MB hard drive with. I need to find some disk software that allows me to map over the FAT limitation of 500 MB of the drive. That question later.

My main question now is. I was wondering do I need to shop for an identical AMI 486 dx2/66 cpu or can I just buy any Intel 486 dx2/66 cpu and adjust the AMI BIOS ? I know AMI 486 dx2/66 cpu will work since my motherboard manual said it will take 486 dx2/66 running 33 mhertz 3.3 Volts or 486 dx/50 running 25 mhertz 5.0 volts. I already tried 1 486 dx2/66 cpu with a heatsink on so I can't see if indeed it was a 486 dx2/66 and it continues beeping when I power on. I double-checked I align the right notch and careful not to get static on the chip. It costed me $10.00 so I already returned it. Ebay is cheaper.

Also tried to a mother board replacement with 486 dx4/100 but, I was told I need to re-install win95 on the HD. I think upgrade to 486 dx2/66 is the most logical step for me to do. And it should double my performance, right ?
I am looking for simple answers like whether I can just buy an intel 486 dx2/66 and adjust the AMI BIOs settings. Difficult to hunt down an exact AMI 486 dx2/66 for sure but if someone can sell me one, I think it should wok !
