Known issues
- VRM module required for expanded CPU support
Without an add-on VRM module this motherboard supports none or only a limited selection of processors. With the installation of a VRM module additional voltages can be added which allows this motherboard to support a wider range of processors.
For Socket 5/7 Pentium VRM Motherboards see the new S7-VRM design by NecroWare. 1) https://github.com/necroware/s7-vrm
Notes
WARNING : No BIOS recovery mode is available on this motherboard! Flashing the wrong BIOS will render the motherboard unusable unless the BIOS chip is removed and reprogrammed.
- Possibly Intel's first ATX motherboard.
- May optionally include S3 Trio64V+ onboard video and/or Crystal CS4232 onboard audio.
- AMI BIOS seems only to work with Intel CPUs.
- With MR.BIOS the system seems to POST with AMD K6-2, but the CPU is incorrectly detected and L2 is not working.
