I have a Northgate 386/16Mz system and would like
to find some way to increase the CPU performance.
I have 1Mb of memory and would like to find some
software to shadow my ROM and see if that helps.
Is the shadowing option usually in the BIOS itself?
My machine boots with the option to change the setup
or do diagnostics built in (courtesy of AMI I think)
but it does not offer the shadowing option.

I'm also considering getting more memory.  Due to
motherboard considerations it will be cheapest to 
replace my 1MB of memory with 4MB DRAM's.  Can you 
increase the performance by buying faster memory?
Does the rating on the chip refer to the maximum,
tested, error-free speed of the chip ?  What controls
the memory speed?  Can that be upgraded so memory
fetches will be returned faster?

A software Engineer, a hardware literate (but not a guru),

Thanks,

Greg
