I checked the ftp.distributed.net site a few minutes ago, and only saw
the rc5des380-x86-dos.zip client.

Good news, though (I think)... after some experimenting, I discovered
that I could get the client to run.  I took out the "noexitfilecheck=1"
line in the .ini file (which I always add now), and I ran the client
with the command "rc5desd -runbuffers".  The client has been running
for about 24 hours now, and is 50% done with its first block (of 2^30).
Both those steps were necessary to get the client not to crash.

If at all possible, I'd certainly like to see DES clients with 386/486
optimizations.  The PS/2 does about 6.2kkeys/sec on RC5, or 2 blocks
per day.  I was hoping that the 10 DES blocks I fed it would be finished
some time before the contest ends. :-(
