BIOS A04 is available for download at http://support.dell.com/filelib. It
has support for PXE and can be put on all your 1550s.

BIOS Bug. 1) upgrade to A04, 2) Turn off serial redirection in LILO, and
get rid of the "message=" line. The BIOS will handle redirection of the
LILO prompt for you and everything should work fine.

Dell sells the Dell Remote Assistant Card (DRAC) which supports lights-out
managment. On the, 1550s though, there are a couple of drawbacks to using
them. First, I believe that you can only run single-processor because DRAC
physically conflicts with the heat-sink on one cpu, also, it will be
several weeks before Red Hat Linux 7.1 is supported. Talk to your
salesperson for more details on the features of DRAC.
