Hi all,
I have a few questions about diskboot.S.
Here is the last few lines of this file:
/* fill the first data listing with the default */
blocklist_default_start:
/* this is the sector start parameter, in logical sectors from
the start of the disk, sector 0 */
.long 2, 0
blocklist_default_len:
/* this is the number of sectors to read. grub-mkimage
will fill this up */
.word 0
blocklist_default_seg:
/* this is the segment of the starting address to load the data into */
.word (GRUB_BOOT_MACHINE_KERNEL_SEG + 0x20)
firstlist: /* this label has to be after the list data!!! */
Question:
1.I want to know how the value of blocklist_default_len is filled.
2.Is blocklist_default_len equal to the size of kernel.img?
3.Is it passible to get the size of kernel.img and use it as one of some
parameters to hash kernel.img in diskboot.S?_______________________________________________
