Yes, it's a huge a big difference... Off the ProLiant I can FTP files at 
about 8MB/s, so I'm not expecting 10MB/s, but give me at least 6 MB/s, 
then I'll be happy!

I remebering checking the BIOS before I installed the system, and I 
don't remeber anything about DMA on the Network adapter, but I'll have 
another look when I can. The thing is, wouldn;t a DMA issue limit teh 
FTP to 1.5 MB/s as well as samba?

You have a compaq ppro 200 somewhere? Cool... If you get around to doing 
some tests let me know what you get! If you're doing a fresh install try 
it with XFS (you must pass xfs to the kernel at the instalation boot 
prompt), if you have trouble detecting all of your memory at boot up (I 
did) try passing memmap=xxxM at XXM, where XX is the amount of memory the 
kernel detected and xxx is your total memory minus the amount detected.
