I do not currently have a machine that can boot from either usb or network, and that includes this $300 Asus mobo with a quad core phenom on it. So ATM, the only universal boot to install method I have is to maintain a working internal optical drive in every box. > D525 is good for EMC, yesterday I counted that I have used D525 in 4 > EMC machines.

I followed that discussion rather closely, but for steppers it doesn't appear that fully working EPP is required. In fact, I have no clue what mode that Startech card I am using so nicely is actually in. I plugged it it, reset the address to "0xd000 out " in the .hal file and it Just Works(TM) This current box I run emc on, I left the latency-test running when I went to bed the first time. Amanda has since been fired off and made a level0 backup of the important bits of the install, and that ran the jitter up well past 100 u-secs, 105 TBE. So it doesn't look as if I should be leaving it running a critically busy overnight job. The one job I did have it do overnight involved very slow motions as it ran a diamond wheel just barely touching the teeth of a carbide toothed table saw blade that needed a tuneup. The blade worked well, but I have since found a better one, a CMT branded one with ATBF teeth. Sweet, no burns even in cherry. Cuts take finish directly from the table saw. Thanks Viesturs.
