Hi!
At first thanks for your great work!
I started to make multiboot CDs 1,5 years ago, with Bart Lagerweij 's utils.
I have a problem with the memtest86 floppy image, made by the authors in the
.zip file, downloadable from it's homepage, when I use diskemu. Some days
ago I found on Bart's page a new method to select boot images on CD with
syslinux/isolinux/memdisk. I thought this is my solution! With LiLo I could
start the memtest86 image from hardisk, but with diskemu I couldn't. The
error number was 8000, and now it's the same when I tried to boot with
isolinux/memdisk. A part of my isolinux.cfg:
label 5
kernel memdisk
append initrd=memtest.img
I read the source of syslinux-1.67 - syslinux-1.75, and the memdisk
documentation segment of http://syslinux.zytor.com/ .
I think, I should to use a memdisk command line option "floppy" (?).
How is it correct?
label 5
kernel memdisk
append initrd=memtest.img floppy
or
label 5
kernel memdisk
append floppy initrd=memtest.img
or any other?
Thanks!

However, if I use just the 84kb memtest.bin image image that memtest86.org provides, then it doesn't work for me, even if I supply the floppy option. Note, that I wouldn't necessarily expect it to, since the 84kb image isn't even an integral number of sectors! I did try to get this to work just by padding the image to a whole number of sectors -- rather than to the full 1440KB -- but without success (though I have to admit that I didn't try very hard, so I could have been doing something stupid). -roy

If you use a floppy image you have to contact the author of the floppy image or look into it to see how it's built, what it expects (it seems you're saying it expects parameters). My advise is to use just the memtest binary as a kernel image. -- giulioo at pobox.com
