Re: NetBSD -current/-8 EFI CDROM boot on SuperMicro A2SDi broken
I debugged something more.
The BIOS cliad the CDROM device is a hard disk - so all our bootloader
assumptions about no labels on non-harddisks (CDROM, FLOPPY) don't hold.
Thus biosdisk_open operated on a fake label with block offset 0 and thus
no access to the file system.
Then I put an install-image (8.99.4, -8.0_BETA) on a USB stick. Here I
get into the boot loader - good. booting loads the kernel ... and then:
Famous last words:
Welcome to the NetBSD/amd64 8.99.4 installation image
ACPI (Advanced Configuration and Power Interface) should work on all modern
and legacy hardware. However if you do encounter a problem while booting,
try disabling it and report a bug at http://www.NetBSD.org/.
1. Install NetBSD
2. Install NetBSD (no ACPI)
3. Install NetBSD (no ACPI, no SMP)
4. Drop to boot prompt
Choose an option; RETURN for default; SPACE to stop countdown.
Option 1 will be chosen in 0 seconds.
Nothing on VGA (consdev pc) or the SOL redirected com ports
(com,0x...,115200). Looks like early trouble in startup or EFI.
Same behavior with -8.0_BETA from yesterday.
So I think we are looking at two issues:
1) bootloader when the device type from BIOS is HARD_DISK for CDROMs.
2) starting the kernel from the EFI bootloader does not seem to
work on this machine (possibly others)

It would probably help to see your partition information.
