Got your point ... My comment was based on the fact that there has
been no 486 since 1995 ! Old hardware is not very reliable for a
critical thing like an ICU ! I don't mind a HDD dying, but defini-
tely not a man because the HDD died and the last blood sugar level
could not be accessed :-)
It is neither the technology nor software adequacy the delimiting
factor. Merely the reliability.

Don't know if you are following the thread. The box he is talking
about is a 486 with 8mb RAM without a CD-ROM. The only mode to go
in is through floppy. The HDD is also small .... He would have to
face several problems:
a) Installing a current distro suitable of taking current SQLs.
b) Managing his partitions etc.
c) I had suggested Pygmy Linux which is on kernel 2.2.16 and the
full distro works from a dos drive (UMSDOS/loadlin) with just
9 odd disks. Pygmy linux does not have a boot CD. Just unzip
the file on the M$ partition and you are running ! This can be
done on an existing M$ only.
d) Once in Pygmy, you have all the Linux tools available to do
stuffs like repartitioning, creating seperate swap etc, and
not before.
e) Change to ext2 was advocated for speed reasons. I suggested a
bigger /home because he wants to run SQL only, and postgres
data goes in /home/postgres. His drive space is premium. I do
not know much about mysql.
f) If he has access to the Slack root/ boot disk sets, he can do
as you say ... he would still have to install M$ first though.
Why take the trouble ?
