I'm guessing this is too modern to qualify as "vintage", but as a novice to all this I'm unsure if there is anywhere better to ask?
I'm trying to resurrect a Chicony MP989 laptop, my first computer, dating from late '98/early '99. I've learnt it has an i440bx chipset and I'd like to upgrade the cpu from the present Pentium II 266mhz to make it more useable, but I haven't been able to find any solid info about how the dip switch settings change on the main board for different cpu frequencies. I've found them for the i440 on other boards, but not much directly relevant to the Chicony. Chicony in the US and Germany have not been able to provide any documentation as they stopped laptop manufacture over 10 years ago.
If anyone can help, point me in the direction of someone who can, or where I might find a service manual, I'd be very grateful.
