iso efi boot with memdisk - Aigor - 2021-05-08 09:24

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 menù 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

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.
