H. Peter Anvin	463c9a9f7d	[x86 setup] EDD: add missing =m constraint ... Add a missing =m constraint to the EDD-probing code, that could have caused improper dead-code elimination. Signed-off-by: H. Peter Anvin <hpa@zytor.com>	2007-08-02 13:45:49 -04:00
H. Peter Anvin	ff659d13ed	[x86 setup] EDD: Fix the computation of the MBR sector buffer ... Some BIOSes require that sector buffers not cross 64K boundaries. As a result, we compute a dynamic address on the setup heap. Unfortunately, this address computation was just totally wrong. Signed-off-by: H. Peter Anvin <hpa@zytor.com>	2007-07-31 16:18:05 -04:00
H. Peter Anvin	d13444a5a5	EDD probing code for the new x86 setup code ... Probe EDD and MBR signatures, in order to make it easier to map physical hard drives to BIOS drives. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>	2007-07-12 10:55:55 -07:00
