Just a short update on this machine (Acer Aspire X1470) and the GPT / UEFI
situation.
Today I set up another partition, EFI system partition. The partyitions now
looks like this:
root@kg-vm2# gpart show ada0
=> 34 250069613 ada0 GPT (119G)
34 128 1 freebsd-boot (64k)
162 119537664 2 freebsd-ufs (57G)
119537826 8388608 3 freebsd-swap (4.0G)
127926434 121634816 4 freebsd-ufs (58G)
249561250 204800 5 efi (100M)
249766050 303597 - free - (148M)
I formatted the partition like this:
root@kg-vm2# newfs_msdos -F32 /dev/ada0p5
newfs_msdos: trim 50 sectors to adjust to a multiple of 63
/dev/ada0p5: 204512 sectors in 12782 FAT32 clusters (8192 bytes/cluster)
BytesPerSec=512 SecPerClust=16 ResSectors=32 FATs=2 Media=0xf0 SecPerTrack=63
Heads=16 HiddenSecs=0 HugeSectors=204750 FATsecs=100 RootCluster=2 FSInfo=1
Backup=2
I have tried putting an EFI shell on it (I got the idea from this[1] page, I
have tried both the 1.0 and 2.0 x64 shell), like this:
root@kg-vm2# mount -t msdosfs /dev/ada0p5 /mnt
root@kg-vm2# ls -l /mnt
total 848
drwxr-xr-x 1 root wheel 8192 Aug 3 14:30 EFI
drwxr-xr-x 1 root wheel 8192 Aug 3 16:21 boot
-rwxr-xr-x 1 root wheel 847232 Aug 3 14:56 shellx64.efi
root@kg-vm2# ls -l /mnt/boot
total 760
-rwxr-xr-x 1 root wheel 771072 Aug 3 16:23 bootx64.efi
root@kg-vm2# ls -l /mnt/EFI
total 16
drwxr-xr-x 1 root wheel 8192 Aug 3 14:30 FreeBSD
drwxr-xr-x 1 root wheel 8192 Aug 3 15:06 boot
root@kg-vm2# ls -l /mnt/EFI/boot
total 760
-rwxr-xr-x 1 root wheel 771072 Aug 3 15:29 bootx64.efi
but no dice - it is not working, it still prints "ERROR: No boot disk has been
detected or the disk has failed."
when I try to boot from this disk.
How do I figure out where this UEFI firmware that Acer has put in this machine
is getting it's boot manager and or boot loader from?
I tried running 'strings -f' on the BIOS file (sorry, UEFI firmware), that got
me all the EFI error messages, but nothing useful.
Googling didn't help either.
