Yes, that was a typo. I've tried with and without the (correctly spelled) --no-describe parameter.

Uncompressed. I saw that from another forum post here and verified it.

Quote:If this image boots with syslinux, I'm assuming you're using memdisk to load it. If you try to load the same floppy image using memdisk via ipxe, does it load properly?

It does not. I get a "Decompression error output buffer overrun" error message. (This does not happen when I use memdisk and pxelinux, only memdisk with ipxe).

To summarize:

Existing uncompressed floppy disk images, created per these instructions:

syslinux and memdisk (using "APPEND floppy"): works correctly.

ipxe and memdisk: Throws "Decompression error output buffer overrun" error.

ipxe and sanboot: hangs as originally described.
