Wondering if possible to add non-Fedora options to EFI boot menu with some
method similar to the 40_Custom. Thanks.
I've maintained a project on Sourceforge going back to 2004, and it was
originally a cd only boot option, but over years create usb and ability to boot
directly from grub2 menu using 40_custom.
Few years ago, created EFI boot options that work with cd and usb using
grub4dos and grub4dosefi as boot loaders. Have looked for a process similar to
40_custom for EFI, but have not located anything.
The 40_custom is very simple.
# !/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
menuentry G4L_Version_0.62_video_800x600 {
set gfxpayload=800x600x16,800x600
linux /bz6x0.12 root=/dev/ram0 telnetd=yes
initrd /ramdisk.lzma
}
Has the kernal file and ramdisk.lzma in the /boot directory and loads program
directly from grub2 boot menu.
With grub4dos regular boot the menu has this for booting.
title G4L - bz6x0.12 - with vga=788
find --set-root /linux/bz6x0.12
kernel /linux/bz6x0.12 root=/dev/ram0 vga=788 telnetd=yes
initrd /linux/ramdisk.lzma
Also have this to run memtest since regular Fedora one doesn't seem to work??
title memtest
find --set-root /memtest86+-5.31b.iso
#Uses memdisk from syslinux 6.04pre1
kernel /memdisk iso
initrd /memtest86+-5.31b.iso
In the EFI/grub/menu.list have to boot. memtest doesn't work with the EFI boot
so no option for that.
title G4L - bz6x0.12 - Version 0.62 Default Screen Resolution
find --set-root /linux/bz6x0.12
kernel /linux/bz6x0.12 root=/dev/ram0 telnetd=yes
initrd /linux/ramdisk.lzma
Hi Michael,
As I understand it, /etc/grub.d/40_custom can be used equally with
UEFI boots and legacy boots.
regards,
Steve
