Subject: int 0x15, ah=0x88 question
Date: Mon, 19 May 2003 12:22:07 +0200 (MEST) [thread overview]
Message-ID: <9188.1053339727@www54.gmx.net> (raw)
Hi all,
Following code comes from arch/i386/boot/setup.S (memory detection):
387 movb $0x88, %ah
388 int $0x15
389 movw %ax, (2)
Why memory address 2 is used? Where else in the kernel is it used? We are in
real mode, so (2) should be the same as %ds:(2), or not?
Sorry that I'm bugging the mailing list with that question but I didn't
found the answer anywhere. So a web page, a book or something else would be also
nice as an answer.
Regards,
Andy
