Linux Alpha - Jensen

Also known as DEC 2000/DECpc 150/Highscreen AXP (bad picture)

The Jensen is different! This is because the Jensen is one of the first PC style Alpha machines developed by Digital. The design is experimental in some ways and does not always follow PC standards. But Linux runs fine on it!

• Alpha 21064 CPU @ 150MHz
• 512kB external 2nd level cache
• 8 PS/2 SIMM sockets, true parity needed for ECC, four SIMMs per bank
• one on board parallel port
• two on board serial ports (currently only the first is usable with Linux!)
• six EISA slots, special ECU disk needed (EISA Configuration Utility)
• PS/2 connectors for keyboard and mouse
• non standard board, special power supply and enclosure needed

• Hardware Reference Information (ek-a0638-td 1MB PDF)
• Jensen section of the Alpha FAQ (http://www.azstarnet.com/~axplinux/FAQ-9.html)

• Optimal hardware options for Linux
• The Jensen is a beast when trying to install it from scratch. Here is a hopefully helpful step-by-step manual I once wrote for RedHat 5.0.
• You might also want to have a look at the installation hints and files at ftp://ftp.digital.com/pub/DEC/Linux-Alpha/JENSEN_INSTALL/ You can also obtain firmware V1.7 from there!
