I am using a bootable CD ISO of Plan 9 that I downloaded last night so things should be current. The system has two 130GB hard drives installed. Everything works under Debian Linux. *** Plan 9 is not able to detect the hard drives. *** Here is what I see during the boot process: PBS1... Plan 9 from Bell Labs ELCR: 0C20 islba: drive 0x80 extensions version 33.0 cx 0.5 extgetsize: drive 0x80 info flags 0x1 bios0: drive 0x80: 137,438,952,960 bytes, type 3 islba: drive 0x81 extensions version 33.0 cx 0.5 extgetsize: drive 0x81 info flags 0x1 bios0: drive 0x81: 137,438,952,960 bytes, type 3 reading drive 0x80 offset 0 into seg:off 600:0... biosdiskcall: int 13 op 0x42 drive 0x80 failed, ah error code 0x80 sectread: bios failed to read 512 @ sector 0 of 0x80 probing cd...dev A0 port 170 config 85C0 capabilities 0F00 mwdma 0407 found partition sdD0!cdboot; 52978+1440 reading drive 0x80 offset 0 into seg:off 600:0... biosdiskcall: int 13 op 0x42 drive 0x80 failed, ah error code 0x80 sectread: bios failed to read 512 @ sector 0 of 0x80 reading drive 0x80 offset 1 into seg:off 600:0... biosdiskcall: int 13 op 0x42 drive 0x80 failed, ah error code 0x80 sectread: bios failed to read 512 @ sector 1 of 0x80 During the partdisk step of the install process Plan 9 only sees sdD0 as possible disks. I have tried saying "yes" and "no" to DMA for disk drives before the windowing system starts up and there is no difference in detected disks. Does anyone have any suggestions as to what I might to do overcome this problem? I would appreciate anything here as I am flying pretty blind. I am running the most recent version of the BIOS (A10) from Dell. Thanks in advance, Matt
