Right. Dave's problem, as I understood it, was that the BIOS only saw 32MB of memory. In that case, telling the kernel that there is 128 would cause it to attempt to access memory that has not been addressed by the BIOS, and would thereby crash the kernel. In your case the address space did exist, the kernel just didn't recognize it by default. >I had a compaq workstation with 128meg of ram. Bios saw 128 meg but linux would not see more than 64m, reguardless of what kind of memory or how I arranged the simms in the box. In the end I put in at the end of loadlin.exe mem=128M That took care of everything!
