440FX DRAM-to-PCI DMA bandwidth

[jhoe@juicy-juice.lcs.mit.edu (James C. Hoe)]

Hi All,

Does anyone know the peak DMA bandwidth from DRAM to a PCI master over
the Intel 440FX chipset?  Has anyone seen more than more than
~41MB/sec when transferring in this direction?

I am using a dual-PII Dell PC with 440FX chipset and EDO DRAMs.  I
know my PCI master can do better than 41MB/sec and would like to know
if there anything I can do to the PC to boost the DMA performance.  I
have been playing with DTE and DTD bit of 440FX's DBC register, but it
doesn't seem to make any difference.

Thanks,

James
