Someone set up a wrong BIOS geometry of 54 heads and 6 sectors (by setting up the corresponding MBR in /dev/rsd2). 13045 is just total_sectors / (54 * 6). >What bother me a lot is why libdisk/sysinstall don't see the slices when >disklabel can ! disklabel(8) knows/shows nothing about slices (or BIOS geometries). >I can mount every slice on that drive without problem so >the kernel has the right label but why disklabel is the only program to >display it correctly ? libdisk/sysinstall must be wrong. The 54/6 geometry should work if there are no booting problems. Bruc
