[syslinux] How to boot a compressed CD-ROM image from disk

[Blaauw,Bernd B.]

Please keep this on the mailinglist.

You CANNOT *boot* an ISO file (except when presenting it as a cdrom device in an emulator like QEMU/Bochs/Vmware etc..).
You CAN mount it, probably by using an initrd.

What you do is:
-network boot
-obtain pxelinux.0
-obtain pxelinux.cfg
-make selection (Linux)
-boot Linux kernel and a proper initrd
-obtain network access
-mount the ISO file on the network as a local drive
-access the ISO and execute whichever program(s) you want that are on that ISO file.

So yes, you can install from network. But that does not means 'obtain ISO file from network and boot it like if it was a cdrom disk'.
That might only have worked for something like MSDOS perhaps.

and that's about how far my Linux knowledge goes..
