Select two parameter sets in the BIOS. Increment the values of one of these to match your disk parameters and dekrement the other set to the same amount. This is because most BIOS have a checksum over the disk param table. To find the table is a bit of debug work. I remember the table is located usually at the same spot (where IBM put it in their original BIOS), but I forgot the address. Another possibility: often modern BIOS have the entry 47, which is programmable by the setup. This is of course only possible if you have not already another disk parameter set allocated to it.
