It's definitely the EDD code that causes the delay, though I believe it's a BIOS problem.
I've got one report http://marc.theaimsgroup.com/?l=linux-kernel&m=108797825504429&w=2 from David Balazic with his Gigabyte GA-7 VAXP Ultra motherboard. BIOS version is F6. Disks : - Quantum lct20 20 GB - IBM Deskstar 120GXP 60 GB Both on the Promise PDC 20276 on-board controller, each on its own channel(cable).
where there was a delay, which was variable based on stuff he put on the kernel command line. Likewise, downgrading to BIOS F4 did not exhibit any delay.
I've got another report with this board with a different BIOS where this BIOS version on that board: Motherboard: Gigabyte GA-7IXE4 BIOS version: FAd (that's a beta version) Kernel: 2.6.2-mm1
worked without the delay.
Yours is the first x86-64 BIOS I've heard with a problem. Please provide the disk controller type and BIOS version.

Only that it's now probing more than just the first disk, but the first 16 possible BIOS disks. If the BIOS behaves badly to an int13 READ_SECTORS command, that'd be good to know...
I'm open to suggestions on how to know, from real mode, if a BIOS will misbehave...
FWIW, I'm on vacation this week, with limited email access, but will respond when I can.
Thanks, Matt
