= Working with ISOs =

Let's say you've got a CD ISO, but you want to boot that from the network, because using virtual media over an iDRAC sucks.

Well I forgot I had this page, but I've been wanting it again because I tried to install Pop OS and had no luck with local USB. :/

It get somewhat more complex with UEFI, I think, but here are some notes.

Maybe can PXE this with a pxelinux.cfg/default entry:
{{{
# taken from grub.conf on the iso
menuentry "Try or Install Pop_OS" --class pop-os {
        set gfxpayload=keep
        linux /casper_pop-os_20.10_amd64_nvidia_debug_22/vmlinuz.efi boot=casper live-media-path=/casper_pop-os_20.10_amd64_nvidia_debug_22 hostname=pop-os username=pop-os noprompt  modules_load=nvidia ---
        initrd /casper_pop-os_20.10_amd64_nvidia_debug_22/initrd.gz
}
}}}

How to run tftp server on suomi:
 * /home/furinkan/Documents/tftp_root/uefi
 * sudo py3tftp -p 69
 * Unifi DHCP points to x.x.x.175 and looks for syslinux.efi

I found that Pop's initrd doesn't have support for a ramdisk, so copying Ubuntu's config didn't work with it. Here's some tricky stuff with initrds:
