The ebuild suggests to install memtest.bin with the --type=netbsd option. However, this option should only be used in combination with the (not installed) memtest file. So the grub options that work for me are: kernel /boot/memtest86plus/memtest.bin and kernel --type=netbsd /boot/memtest86plus/memtest The last one requires to install the file memtest as well. It should be installed in addition to memtest.bin, because the first one may cause a grub error 28 on systems where the lower memory is limited. (On one of my systems due to a big BIOS). I'll attach a patch for the ebuild. Clemens Rabe Reproducible: Always Steps to Reproduce: 1. Follow instructions. 2. Reboot and choose the grub entry 3. See the grub error message 4. Remove the --type=netbsd option in grub and try again - it should work. Actual Results: Grub gives an error message about the kernel... command. Expected Results: Should start the memtest86+.
Created attachment 209143 [details, diff] Fix for grub installation instructions and install memtest file as well.
Which version of grub are you using? For me, using grub-0.97-r9, --type=netbsd with the 'memtest' file doesn't work at all.
I'm using grub-0.97-r9 too, just checked by reinstalling it. Are you using a 64-bit version? I'm using the 32-bit stuff.

I have a 64-bit system, yes, but as far as I can tell both grub and memtest86+ are compiled as 32-bit binaries. The -m32 flag is used during compilation, grub is using files from /lib/grub/i386-pc and 'file memtest' says: memtest: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, stripped

Yes, I've compiled and installed both grub and memtest86+ on the amd64 profile, just to be sure, and it still works like charm. Are there any errors from grub, does it reboot immediately or just hang? I suspect the memtest.bin file (without the netbsd stuff) works? Btw, I'm using a separate partition for /boot (hd0,0). Cheers, Clemens

The memtest.bin file works indeed. Grub says that the 'memtest' file has an invalid binary format and returns me to the boot menu screen. Could you please send me your 'memtest' binary to my @gentoo.org e-mail address?

I'll get the grub error 13 (Invalid or unsupported executable format) when using kernel /boot/memtest86plus/memtest or when using the memtest86.bin file with the --type=netbsd option (In the latter case, grub also says that it is a Linux-zImage).
(In reply to comment #7) > The binary should be on its way... OK, so your binary works. It also seems to about 10% in size of the binary I get when building memtest. Could you please post your `emerge --info`?

Created attachment 210934 [details, diff] Patch updated to work with current CVS version 1.5 I've just encountered that there was an update of the ebuild in the CVS, that installs memtest.bin as memtest and creates the symlink memtest.bin -> memtest. The modified patch installs the original memtest file as memtest.netbsd, suitable for the alternative grub "kernel --type=netbsd /boot/memtest86plus/memtest.netbsd" method.
I added your patch to CVS, thanks! It turns out that the non-working ELF binary is a binutils problem. After downgrading to the version you're using, GRUB was able to run it with the --netbsd option just fine.
(In reply to comment #11) > I added your patch to CVS, thanks! Thank you! I have verified that the official ebuild works on my x86 and amd64 system.
