If you replace the 01 with an 02 you get an 'ALPHASERVER 300 SYSTEM BOARD' Co-incidentally it also has 8Sim sockets and comes in the same case as an AS200. I would suggest that you have an AS300. In which case the failsafe loader jumper is J2 which in the position 1-2 will boot an image from floppy. The LED codes are stored in gif files, so I can send them but I'm hesitant to send binaries without confirmation from you. Beep Code Meaning 1-1-4 Basic diagnostic problem. 1-2-1 Real-time clock (BQ3287) failure, or the real-time clock interrupt did not occur. 1-2-4 Hard failure (for example, a Bcache failure). 1-3-3 Insufficient memory. 3-2-1 Header of the flashROM unreadable, or the flashROM checksum failed. Attempted boot failed because either: (1) no floppy in drive, or (2) no boot block on the floppy. 3-2-3 No floppy in drive. 3-2-4 Failure with the keyboard or mouse controller. 3-3-1 Hard failure. Refer to the LEDs to find exact location of failure. Memory Configuration.. You can increase your system's memory to 512 MB (megabytes) You can add 32-MB, 64-MB, 128-MB, or 256MB memory options Each memory option consists of four single in-line memory modules (SIMMs): 32-MB option consisting of four 8-MB SIMMs 64-MB option consisting of four 16-MB SIMMs 128-MB option consisting of four 32-MB SIMMs 256-MB option consisting of four 64-MB SIMMs SIMMs must be of the same capacity and must always be added in sets of four into one of two available memory banks, bank 0 or bank 1 If all SIMM slots are already used, you can still increase your system's memory by removing four SIMMs from one of the banks and replacing them with four larger SIMMs. The system requires 72-pin parity SIMMs that have an access time of 60 ns or 70 ns. SIMM Removal and Replacement Hope this helps Adam
