This is on a non-EFI system. Memtest use to work on my
systems before (Have 5 Fedora 34 machine and the
standard memtest started giving the blue screen when
selecting memtest). The memtest worked fine with
syslinux boot from flash, and use to work with grub4dos
boot, but now that requires a memdisk setup to load it.
Just was trying something similar with grub2.
With grub4dos use this in menu.lst
title memtest
find --set-root /MEMTEST.IMG
#Uses memdisk from syslinux 6.04pre1
kernel /memdisk
initrd /MEMTEST.IMG
in /boot/grub2/grub.cfg use
menuentry 'Memtest' {
insmod part_msdos
insmod ext2
set root='hd0,msdos5'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos5 --hint-efi=hd0,msdos5
--hint-baremetal=ahci0,msdos5 --hint='hd0,msdos5' fa908208-22bd-4031-b620-841498e0708c
else
search --no-floppy --fs-uuid --set=root fa908208-22bd-4031-b620-841498e0708c
fi
echo 'Loading memdisk'
linux16 /memdisk iso
echo 'Loading iso'
initrd16 /memtest86+-5.31b.iso
}
Have tried a little with EFI, but haven't found a way since it doesn't like memdisk??
