SubjectRE: DMA not supported with Intel ICH4 I/O controller?
Date
>Ok, what is the DMA device?  Hard drive?  Can you give details?

Mike,

It's a proprietary board that we use to allow the PC to send blocks of data
to some industrial equipment. We developed the hardware and Linux driver
in-house. This same board works (under Linux) on a MoBo using the Intel
815E chipset (Pentium III) with an IHC2 I/O Controller Hub. This is the
system I did _all_ my stress testing in. The plan was to ship our product
with these ASUS P4PE MoBos (using Intel 845PE and ICH4 controller) and were
un-pleasantly surprise when it didn't work.
