I can mount sd0s1a or sd0a without any problems onto a running system (2.0.5R) from / on wd0a. I can disable both wd0 and wd1 and the bios sees the bootstrap on sd0 and executes it; I can boot /kernel -c and configure it. Alas; the kernel does not get to the point of mounting / (regardless of whether or not -s or -r or both are specified) but rather sits there after it has found npx0 and does nothing. The disk says it has 2061108 sectors on 2700 cyl 9 hd and avg 84 sec but I told disklabel that it is an 8179 x 7 x 36 geometry. Does that make any difference ? Is it OK for sd0s1 to start at sector 0, and is it OK for sd0s1a and sd0s1c to start at sector 0 ? Is there any *documentation* on the workings of fdisk, disklabel, bteasy, the bootstrap code, etc., apart from RTFM and RTFS ? Thanks, Bernard
