We powered up the S/390 for the first time since IBM donated it to the RICM. We were happy to see the BIOS setup screen displayed, but then saw the little message that said that the setup battery was low. We configured the BIOS and rebooted, but it went right back to the setup screen. Most PCs will boot with a dead battery if the AC power is kept on. Oh well, we will order a M4T28-BR12SH1 Timekeeper Snaphat from Digikey and try it again next week.

We bought a new Timekeeper Snaphat from Digikey and installed it on the Pentium server board. The Pentium doesn't complain that the battery is dead, so we made some progress. We configured the SCSI controller, and the Pentium can see the DAT tape drive and the CDROM. The floppy is directly connected to the Pentium board and that works too.

The Pentium does not see any hard drives, so OS/2 doesn't boot. The indicator LED on the SSA controller is blinking, so that means that the SSA controller is not happy with the drive configuration. Mike Ross sent us a copy of the SSA configuration utility CDROM. We should be able to run that utility and then to tell the controller what we have for disks. Hopefully we can recover the existing disk configuration so we don't need to do a fresh installation of OS/2 Warp and OS/390.
