hi guys,
thanks to https://bsdlaptops.wordpress.com/ I was able to enable openbsd boot to efi/gpt environnment managed by grub2 with windows/LMDE5 by adding :
menuentry 'OpenBSD/amd64 normal kernel' {
insmod part_gpt
insmod search_fs_uuid
insmod chain
chainloader (hd0,gpt1)/EFI/Boot2/BSD.BOOTX64.EFI
}
menuentry 'OpenBSD/amd64 ramdisk kernel' --class os {
set root='(hd0,gpt1)'
kopenbsd /bsd.rd
}
to my 40_custom
(with a "toggled" command part to "openbsd data" of the fdisk linux tool, as described:
https://srobb.net/openbsdmultiboot.html )
(obviously you have to add bsd.rd plus bootx64.efi downloaded separately from obsd website to your efi partition with right grub path targeted on them )
This is efficient for gpt disks compliant to full-efi class 3 systems (means no csm, no bios at all)
now, Im looking to do so with mbr/bios disk, as a tri win/nux/obsd boot, does someone have the key to do so?
I thank you vm
