Hello.

I am attempting to transfer data to a PCI card using burst transfers.
The card is configured to map RAM bank at memory location 0xF0000000.
The PCI controller (AMCC S5933) is capable of PCI bursts up to
132Mbyes/sec (theoretical). I have no problems transferring data using
single (protected mode) 32-bit reads/writes, but this produces a maximum
transfer rate of approximately 20Mbytes/sec. Could somebody please
provide (any) information regarding PCI burst transfers. I realise that
this is a generic PCI question, but I am using DJGPP, so I thought that
I would try this newsgroup.

Thanks in advance,

Michael Gillies
