The Acer IPIMB-AR Rev 1.02A is a microATX motherboard built for Intel's second-generation (Sandy Bridge) and third-generation (Ivy Bridge) Core processors.
The Ipimb-ar was a legend in the DIY community, but for all the wrong reasons. It was a proprietary beast, a customized variant of an Intel board that Acer had locked away behind a wall of silence. No official manual existed in the public eye; it was a "ghost board."

Understanding the physical layout of the Acer IPIMB-AR helps prevent errors during installation.
Avoid mixing RAM sticks with different speeds, timings, or voltages. Doing so can cause the motherboard to downclock all memory to the slowest module's speed, or cause random blue-screen errors (BSODs). 7. Troubleshooting: Clearing the CMOS
Acer does not typically publish standalone motherboard manuals for their pre-built systems. The documentation is usually integrated into the manual for the specific computer model (like the Aspire M1935, Predator G3620, or Gateway DX4870).
The BIOS on the IPIMB-AR is the definition of "locked down."
