There must be some system calls to read and/or write a sector on
hard-disk based on an LBA value. FreeBSD's file systems (I expect)
resolve reads and writes to a sequence of reads and writes based on LBA
values. What are these system calls (full argument lists desired)?
I want to check on the boot code that the system sees as it boots up;
running the partition editor will yield the LBA values of the boot1
pieces, and I expect the boot1 pieces to contain the LBA values of the
boot2 pieces.
All of this is because I am getting the messages "Invalid partition" and
"No /boot/loader"; I believe the second one is directing me to the wrong
place, and these messages (from the Handbook, section 5.2) come from boot0
& boot2 respectively. URLs to the source code and makefile's for all
the boots ( 0 thru 2 ) and loader will be appreciated.
