>>>I think there is a bug in the to UTSelectorOffsetToLinear and vice versa functions: >>>I use the from the kernel exported selector to access the physikal RAM addresses at segment 0xD000 as parameter to UTSelectorOffsetToLinear and receive a linear address, ok. But when I access this memory via this linear address on the 32 bit side the data do not reach the physikal RAM, it seems to be a pointer to Nirwana. >>>Can you help me? I'm looking into this – as a posible workaround have you considered using AllocSelector to synthesize a selector that has the same base address and limits as the selector exported by kernel, and then passing this selector (with a 0 offset) to UTSelectorOffsetToLinear?
