PowerPC 7455 933MHz single core. Powermac g4 Quicksilver 2002 Hda has Linux on it with: p1 APM p2 hfs BootBlock 800k p3 ext3fs~98G p4 swap.1G hdb has three sections with hdb 3-9 failing to initiate. hdb 11 to 17 see part below, Extra space. 320G for hdb 1.5 G ram. Boot image will show in OFW boot select screen. READ_DMA48 failure from hdb11- FreeBSD / : UFS2. I/O read failure occurs 75 - 80% of time. Read failure from bootblocks occurs more often. If needed, I can add the dmesg and Xorg.0.logs to this post. They will contain boot up and paths. There is a discrepancy of path unknown- appears as question marks from the Xorg.0.log.
