iso efi boot with memdisk
Hi, im'trying to boot sysresccd iso in a uefi machine, i have already setup dhcp and ipxe.efi with menu, but uefi machine cant boot iso image.
The string i'm using in my menĂ¹ is
Code:
sysresccd-uefi
echo Boot SystemRescueCd ISO
initrd ${nfs-linux-live}/Sysresccd.iso
chain memdisk iso raw
goto start
It ended with
nfs://server/pathiso/Sysresccd.iso ok
memdisk ok
Could not boot: Exec format error http://ipxe.org/2e008081
Could not boot: Exec format error http://ipxe.org/2e008081

Im'trying other solution that implies passing arg to vmlinuz, using imgargs or write argument like this
Code:
kernel images/sysresccd/boot/x86_64/vmlinuz vmlinuz archisobasedir=images/sysresccd ip=dhcp archiso_nfs_srv=192.168.1.9:/volume1/tftproot
it seem that all the cmdline options are ignored and no boot happens.

cmdline is from sysresccd website

Any hints?

Many thanks

RE: iso efi boot with memdisk
Unlikely to get it working this way. This is mentioned in the FAQ.

For the old Gentoo based sysrcd I provided a patch that made it easier to PXE boot.
