Re: Daedalus desktop live: Cannot load memtest

Good find. I'll have to remember to play with that on a multi-boot live-usb that uses syslinux to see what it does.

I don't know if the .bin file is needed. I'll leave it for now and see if someone finds a case where that's the only one that works for them.

Re: Daedalus desktop live: Cannot load memtest

Just a quick note of curiousity:

I don't have an installed version of excalibur, what I do have is a hybrid iso of vanilla using the mate desktop, that I built from a daedalus netinstall, then upgraded to excalibur, it's the same iso I have on my sourceforge for testing purposes.

1. It does NOT have the memtest86+ package installed. No memtest files of any kind in /boot.
2. My machine's BIOS does not have any kind of built-in memtest.

I booted the liveUSB, and at the live grub screen it offers a memtest entry, so I chose that, and it immediately took me to a bright blue screen with all kinds of info going on and began running memtest. In the upper left corner of the screen in large letters was "Memtest86" with a flashing plus (+) sign after it.

So there's some kinda memtest onboard somewhere already, where it is I don't have a clue.

Re: Daedalus desktop live: Cannot load memtest

In the live isos, the memtest images are in the /live directory with the kernel and initrd. That's where you'll find it if you mount the iso on a running system. If you boot the iso, look in /run/live/medium/live (I think that's right.) Poke around and you'll find the boot menus - isolinux/isolinux.cfg and boot/grub/grub.cfg.
