Hello everyone, Today I am trying to install a modified bootstrap loader and fail. disklabel keeps complaining "Warning, revolutions/minute 0" and "super block size 0". After examing the source of disklabel, I find the "super block size 0" keeps me from writing out boot loader. In addition to super bock size 0, the rpm, interleave, trackskew, cylinderskew,headswitch,track-to-track seek, drive data are all zero. This hard disk is a Quantum 540A 516MB IDE one, installed as 2nd hard disk, from cyclinder 236 to 1048 assigned to FreeBSD. And it works fine so far. I just can't figure out why my super block size could be zero. Any idea ? What if I modify disklabel to write out bootstrap loader no matter how my super block size is zero ? Will this ruin my whole system ? -- Yen-Wei Liu (ywliu@beta.wsl.sinica.edu.tw)
