BIOS set for the Dell OptiPlex 7020 desktop, with board identifiers e93839 and KA0121 in the name, including images for both the 4 MB and 8 MB flash chips. Many Intel desktops split firmware across two SPI chips, so each image must go to the chip of matching size. The 6.97 MB RAR is used to recover a machine that will not post or reports ME errors. Read and keep the original contents of both chips before writing, and verify each write with your programmer.
