Microprocessor Restrictions

When upgrading the microprocessors in your system after installing the new micro-
processor boards, do not mix different versions of the Pentium III microprocessor. In
addition, all microprocessors should have the same operating speed and cache size.

Update the System BIOS

Before installing the new microprocessor boards, you must update the basic input/
output system (BIOS), using the bootable flash BIOS diskette provided in this upgrade
kit, or by downloading the latest BIOS from http://support.dell.com. (This download
creates a bootable flash BIOS diskette.) Versions of the system BIOS prior to version
A03 do not support the latest microprocessor versions.
