BTW, one thing I noticed is that, it seems the file downloading from
tftp server for grub2 in uEFI netboot mode is not fast, compared to PXE
netboot.
From the attached file you can see the average rate is about 0.5 MB/sec
in the client ( a VMWare WS 12 machine).
In the PXE netboot mode on the same VM machine, the rate is about twice
faster. Any method I can make it faster in uEFI netboot mode?
You mean, without changing source code? Probably not.
OK, got it.
Oh, yes, please allow me to ask me one more question, I am editing a
grub config to have a local boot:
menuentry "First local disk" --id local-disk {
echo "Booting first local disk..."
set root=(hd0,1)
if [ -e /EFI/redhat/grub.efi ]; then
chainloader /EFI/redhat/grub.efi +1
elif [ -e /EFI/fedora/shim.efi ]; then
chainloader /EFI/fedora/shim.efi +1
elif [ -e /EFI/fedora/grubx64.efi ]; then
chainloader /EFI/fedora/grubx64.efi +1
elif [ -e /EFI/debian/grubx64.efi ]; then
chainloader /EFI/debian/grubx64.efi +1
elif [ -e /EFI/ubuntu/grubx64.efi ]; then
chainloader /EFI/ubuntu/grubx64.efi +1
elif [ -e /EFI/opensuse/grubx64.efi ]; then
chainloader /EFI/opensuse/grubx64.efi +1
elif [ -e /EFI/Boot/bootx64.efi ]; then
chainloader /EFI/Boot/bootx64.efi +1
elif [ -e /EFI/Microsoft/Boot/bootmgfw.efi ]; then
chainloader /EFI/Microsoft/Boot/bootmgfw.efi +1
else
echo "No uEFI image was found!"
sleep 15
fi
Is that possible I can use "search" or other command to make this?
Not that I am aware of; code looks just fine to me.
Thanks. Just think if there is a better way to use "search" to find
those "bootx64.efi", "grubx64.efi", or "grub.efi". Because some vendors
use different path name, like SuSE uses "/EFI/sled12/grubx64.efi", and
in the future, the "sled12" definitely will become "sled13", "sled14"...
For the moment I will keep the way it is.
Appreciate.
Steven.
