>Description:
when I have 4GB of RAM and use the memory remap option then the box panics when trying to mount root. The remap option of the BIOS is ok because I can run it perfectly getting my 4GB with a SATA-II disk. I checked the adaptec card on another PC where remap also worls fine and panics also.
