The BDI2000 config file lets you setup TLB entries. For my 440GX board I have the following in the [INIT] section of the config file: WTLB 0xe0000095 0x1400001B This maps the 32-bit virtual address 0xe0000000 to the 36-bit physical address 0x140000000. A similar incantation should map the PCIX registers into the 32-bit address space, but I don't remember the format of the fields in the command... jeff Jeff Stevens wrote: > Is there any way to access the PCIX Registers using > the BDI2000?
