DMA for Ethernet Controller (Announce)

posted by bretjohn(R) Homepage E-mail, Rio Rancho, NM, 18.04.2016, 17:59

I'm confused about exactly what you're doing.

First of all, why are you using Win32 and not just a "regular" DOS DPMI server? If you're running underneath Windows, you shouldn't need to access the Ethernet controller hardware directly -- just let Windows handle the networking for you.

Secondly, are you wanting to access something in the Ethernet hardware with DMA (like MMIO space), or are you wanting to allocate memory from DPMS that you can manipulate at will and also have the PCI bus read/write?
