Since I couldn't get the patch I don't know what it does, but
the PCI trident 4D wave NX hardware I had surely had DMA address
limitations where MSB 2bits of LBA register are used as other
purposes. I don't know 4D wave compatible controller on Blade 100
removed this limitation.
Marius, does the DVMA base address of blade 100 is lower than 1GB?
