The latest version of the BIOS for the Dell Dimension 8300 desktop computer is A07 ( here ).

The Dell Dimension 8300 computer uses an Intel Pentium 4 Northwood (D1) processor.

The Dell A07 BIOS contains microcode revision 0x21.

The latest microcode that Intel Corporation released for the Intel Pentium 4 processor (FC-PGA2) (CPUID 0xF29, stepping D1) is 0x2E (according to Intel Documentation (Table 1)).

I wish to update the system BIOS with the latest microcode. I have tried using the Intel tool "CHECKUP7.EXE" to update the BIOS with the current microcode, but the utility reported that it could not update the BIOS (BIOS does not implement Intel microcode update API).

How can the system's microcode be updated in BIOS or where may an updated BIOS be acquired?

Coded below are the BIOS Agent 3.66 report and Processors Information section of the CPU-Z 1.45 report.
