Hi,
I am planning to move to MESA cards to drive my mill. AT present I'm trying to
decide between the 7i43 (parallel) or the 5i20 (PCI). Platform will be Intel
D510MO motherboard coupled with a 32Gb solid state disk.
Regards
Andy

On your D510MO board have you tied the rt threads to one core? If so how did
you do this?

AFAIK only for devices that use it for communications, not for
applications which simply twiddle the pins on and off as individual
signals. I might be mistaken.

Currently I am running an out-of-the-box 10.04 liveCD installation.
I think that includes the islocpus=1 boot parameter in grub, but I am
not sure

EPP is ONLY needed for Pico Systems and Mesa products that use EPP as a
communications
path to a controller board. It definitely is NOT

Thanks Andy and Jon, I'm beginning to understand.

I think that the Hostmot2 driver tends to say "EPP not supported,

I think so, but it matters a lot less once you have offloaded the step
generation to external hardware. You don't need the 20,000 nS base
thread, you just need the 1,000,000nS
