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 mgillies AT dgs DOT monash DOT edu DOT au
