BIOS firmware for the HP mt630 mini thin client, packed in a RAR archive of about 4.64 MB. The file name labels the image TRISTAR-A01, which appears to be a platform name and revision, though the name does not explain it further. Thin clients often fail to boot because of a corrupted SPI flash, and reprogramming the chip with a hardware programmer is the usual fix. Read and keep the original contents first, check the flash chip size against the extracted image, and verify the board version before writing.
