Acer BIOS

Acer BIOS is a computer BIOS developed by Acer Inc. from 1987 to 2003 for their own motherboards. Acer BIOS could be seen without Acer branding on other motherboards, but that is only because Acer licensed their motherboards to other OEMs.

Known versions of Acer BIOS
(Chronologically)

Version 4.03
This version of the BIOS has only been found in one instance, an XT clone motherboard made by Acer. It has very few features, a simple memory test, and three colourful text mode rows. It has no setup utility.

This version of the BIOS looks quite different from the rest, which all look alike. The only example of it is also compiled much before the earliest of other Acer BIOSes (1987 and 1993 respectively), which probably means that 4.03 was a different codebase from the rest.
