All memory like DRAM, EDO and SDRAM can be used with Linux. Be aware that older kernels or kernels running on a mortherboard with an older BIOS may only be able to detect 64MB of RAM. If you have this problem, when you add more than 64 Mb of memory you have to add the following line to your LILO configuration file:
So when you have 96 MB of memory this should become
append="mem=<number of Mb>M"
Don't use a number higher than the amount of RAM you really have. This will cause crashes.
