Thank You All Very Much
I have loaded Ubuntu 6.10 on the Opti Plex PIII's - 600mhz, and it appears to work rather well for now.
Not sluggish at all that I can see.
Only issue I had was the CS4236 sound card.
Able to resolve that: login at the terminal - sudo
chmod 666 modules
vi the file and add
snd-cs4236 (found that info somewhere around here I think - thanks)
chmod 644 back rw-r-r
reboot, sound works
Next Ubuntu challange will be printers, or modems I suppose.
These have built in NIC's and it picked that right up.
I'm trying the 2007 on a PIII 1GHz, 256RAM, 40gig hdd.
Been loading since this afternoon...copy the files to hdd...gosh it is slow, but read somewhere be prepared to spend over 3 hours on it.
On the startx, I guess I can download that if needed?
Anyway, again, many many thanks
