Notes:

Never officially released. These seem to be pre-production boards.

Problems include: instability with the full amount of memory, inability to deliver with AGP Pro slot (even 1.5V didn't operate properly), no PCI64 slots, slocket adapters not working at all.

May have been the predecessor to M25C for server motherboard and M25D for workstation motherboard.
