I have the same ISO compressed in several ways: gz and isz.
But in some works just as ISO, in other also as gz and in none as isz.
Why?
i use:
KERNEL memdisk
APPEND iso
INITRD /test.isz

What is the isz format, and where did you read that it should be supported?

You are missing a LABEL, here.

MEMDISK supports gzip and pkzip, as far as I know. Which tool/command are you using to compress the .ISO?

mkisofs or 7zip
it is strange that the same file compressed with the same configuration on a stand it works and another does not.

ok,
maybe I 'm confused with grub.

MEMDISK is not GRUB.

mkisofs or 7zip

mkisofs can build .ISOs, but what mkisofs command-line are you using to compress an .ISO?

7zip offers a variety of compression types, as far as I know. Which "archive format" did you choose with 7zip?

I don't understand what you mean. What is "a stand"?
