Hi Folks, I am working on porting our existing NDIS2 DOS Ethernet driver from IOPort to MMIO mode. But, the PCI MMIO Base address is > 1MB (typically 0xFEBFF000). hence i will need to access it using DPMI services. where can i find this? the CWSDPMI.EXE that runs under DOS cannot be used as it does not support 16-bit DPMI. is there any other tool? thanx HARISH V *A calm sea does not make a skilled sailor. *
