EISA Address Mapping
The pages of EISA I/O address space are mapped to physical addresses 0x0001 0000 (slot 1) through 0x0004 0000 (slot 4). The 112 MB of EISA memory address space is mapped to physical addresses between 0x000A 0000 and 0x06FF FFFF.
Addresses in these ranges can be mapped into the kernel address space for PIO or for DMA (see "Kernel Functions for EISA Support").
