The GRUB2 「memtest86+」 bootmenu option in both 「wtf ist hallowe’en」 and Grml “Hello-Wien” does not work as-is (note that Grml uses ISOLINUX, unless you either select GRUB2 from the boot menu or dd(1) it onto a USB stick, CF/SD card, etc. for manifold-boot) because nobody told the Grml team that it must now be booted with 「linux16」 ipv 「linux」 – fix is to type ‘e’ to edit the entry, move right, type the “16” and hit ^X to boot. Just great… I’ve updated the article accordingly.
On the bonus side, I’ve tested the netboot.me 17001 boot, as well as the ISO (both file – in qemu – and CD-R on real hardware) on a SPARCstation 20, Setup (i386) on a VIA C7, grml and Live (i386) on an IBM X40 and in qemu… so I’d say it works. Oh, and memtest86+ on X40.
Netboot instructions: boot, e.g. via “qemu -m 256 -fda netbootme.dsk”, do not hit Ctrl-B, but hit the Anykey when it asks, “boot a configuration directly”, type 17001 and hit Enter; wait for the “boot> ” boot(8/i386) prompt, type “b bsd.rd” and hit Return. Voilà! (Or, select MirOS bsd4me, which loads a memdisk-ISO, either via the number 2038 or via “Live OSes” → BSD → “MirOS bsd4me current” and just press Enter on the prompt. The gPXE image can be dd(1)d onto a floppy disc.
Benny finally made ports/print/ttftot42 – thanks!
