[Fw_Os_Forum] Using Multiple caddied disks to teach students OS installation etc

Complete guess: "caddied" hard drive support is probably not a default
feature of a stock BIOS or UEFI. Your BIOS had disk caddy support, but
your UEFI does not. Ask your caddy vendor for new firmware support.

As a workaround, how about dropping into UEFI Shell, using startup.nsh
to run appropriate shell commands to mount the various disks, instead of
hoping the firmware will do what you want. At least with UEFI, you have
a chance to fix things in shell before OS starts. If you can't
see/access these drives from the UEFI Shell, then I presume you will
need a caddy update to your firmware.

Again, complete guess. :-)
