Adding memtest 6.01 to Fedora 37 Installation ISO image..

[Michael D. Setzer II]

In a test was able to get memtest 6.01 to work from 
modified regular boot of image, but trying from UEFI 
boot under Virtual Box it doesn't bring up menu, but 
brings Shell options.

Process get memtest files from 
https://memtest.org/
https://memtest.org/download/v6.01/mt86plus_6.01_64.grub.iso.zip
Use isomaster to extract two memtest files from boot and uefi directories and 
create following unique names.
144344 memtest.leg
144384 memtest.uefi

Use isomaster to modify Fedora-Workstation-Live-x86_64-37-1.7.iso

Added two memtest files to /images directory
and modified /boot/grub2/grub.cfg to add
menuentry 'Memtest Legacy' {
	echo 'Loading memtest 6.01 for BIOS BOOT SYSTEM'
	linux /images/memtest.leg
}
menuentry 'Memtest UEFI' {
	echo 'Loading memtest 6.01 for UEFI BOOT SYSTEM'
	linux /images/memtest.uefi
}

Saved the image as Fedmem.iso after additions.
Booting as legacy option under VirtualBox the memtest options will both work 
fine to bring up memtest. With grub4dos boot, the memtest.leg only works with 
a legacy boot, and memtest.uefi only works with UEFI boot.

Tried to boot modified Fedmem.iso, but in UEFI boot mode it brings up a Shell 
versus bringing up the menu as the original iso does. Probable dealing with 
changes in image, or perhaps the name of iso being different. 

I believe at one point memtest was include with boot iso. Know I've occasionally 
had machines with memory issues, so generally ran memtest on them if didn't 
know memory was good. 

Perhaps if memtest programs were added using Fedora build, the efi option 
would work. 

Just wondering. Have the memtest 6.01 work on both install Fedora 36 and 
Fedora 37 machines from grub menu. Have put info on bugzilla report as well.

Thanks. Perhaps someone with more experience with UEFI. Only have two 
machines using UEFI boot, and do testing with Virtural Box on images.
