What provides the cd9660 driver to FreeBSD? When you load the .iso over a network card, aka PXE/HTTP, the code that does that usually creates a ram disk and a "fake cd drive" that stops working as soon as you stop running the PXE code, which means the device does not show up while the kernel is probing. FreeBSD simply does not support bios devices in this manner, unless something has changed I am totally unaware of. -- Rod Grimes rgrimes_at_freebsd.orgReceived on Tue Jun 16 2020 - 14:09:42 UTC
