This page is about the proprietary BIOS developed by Acer from the late-80s to the early-2000s. For other types of BIOSes used by Acer computers, see AMIBIOS, AwardBIOS and PhoenixBIOS. For UEFI firmware used by Acer computers, see AMI Aptio and InsydeH2O.
Acer used to develop its own proprietary BIOS from the late-80's until about 2003. This BIOS was used on most Acer computers from that era. Computers of that era from other OEMs using Acer motherboards, including some IBM ThinkPad models manufactured by Acer, also used this BIOS. Occasionally, though rarely, it was also used on some AOpen motherboards (such as the DX2G Plus which is an Acer rebrand), mainly as AOpen is a sub-brand of Acer.
Around 2001, Acer discontinued this BIOS on most of their newer desktop computer models and motherboards in favor of AwardBIOS (mainly versions v4.60PGMA and v6.00PG). Their newer desktop models with ECS Elitegroup motherboards also typically used AMIBIOS 8 and later on AMI Aptio (UEFI). Meanwhile, their newer laptops usually had either PhoenixBIOS or InsydeH2O, with the latter becoming an almost exclusive choice later in the UEFI era.
However, despite this, newer instances of Acer's proprietary BIOS do exist, with the latest known instance being compiled on November 10, 2003 for the Wistron M51SG motherboard (Wistron spun off from Acer in 2000)[1].
