Memory Problem

Old Compaq 575Deskpro,75MHz CPU. Trying to add more memory to the 16 MB that's installed now. But no way will the sys accept more memory without stoping computer from booting. I get the message about vxd files and reload windows. System will run fine with the 16 MB installed. At boot system will count additional memory then I get the screen to accept the new settings all this seems to work OK but when starting win sys stops and reports the vxd problem. I cant get into the BIOS by hitting the F10 key or by removing the battery/hdd cable ets. Just reports that sys settings have changed and if I want to accept. Does this sys need a {setup disk}??? I have been to Compaq web site but couldent find any info.
Thanks

 

I haven't checked their site, but I think the memory has to be EDO. I had similar problems with a 90mhz. Once I got the correct memory, everthing was ok. By the way did you make sure the memory was setup properly in bios?

 

These old (or newer for that matter ) Compaqs don't really give you access to the bios like other machines. I had an old 75 MHz compaq that i had 24 megs of ram in. I just put it in, and the machine changed the settings for me. Sounds like it could be bad ram. Have you tried the new ram by itself?

 

What kind of memory do I need?
When choosing among ECC, parity, and non-parity memory, you need to match
what is already in your system. You can tell which kind you have by looking
at one of the modules currently in your system. Count the number of black
chips on one module. If the number of chips can be evenly divided by three
or five, you should buy ECC or parity (whichever is offered for your
system). If not, you should buy non-parity.
For example, if one of your modules has nine chips, you should buy ECC or
parity. If one of your modules has eight chips, you should buy non-parity.

Found this on another help site and maybe this will help you get the right memory for your computer
