Hi all:
I am very very new to kernel hacking. I have been reading lurking on
this list for some time and have to commend all you guys for the great
and friendly atmosphere.
As I was reading the bootstrap code (bootsect.S), I came across :
movw $BOOTSEG, %ax
movw %ax, %ds # %ds = BOOTSEG
movw $INITSEG, %ax
$BOOTSEG gets assigned to %ax which gets assigned to %ds. I am also new
to assembly, but could the first two lines be made into a single line like
movw $BOOTSEG, %ds
Is this possible? or is there a reason for it going through %ax, which
appears to be a redundant middle-man since its immediately overwritten
in the third line.
movw $INITSEG, %ax
Thanks.
