[Flea]

Hi.. Heres my question I have an old Aptiva 2153-E2U it has a k6-2 333 in it. I want to upgrade the cpu with the fastest amd chip my motherboard can handle (Ali M1542-M1543) Can anyone please help me btw IBM was no help since they dont believe in upgrading CPU. Or if possible direct me to a site that could cause I figure i'll need to also know which switches on the motherboard got to be reset. Any and all help welcomed. Thanks.
