Re: install/60342: netbsd_11_0_rc4 dvd can't boot and prompts for a floppy attempting install to bare SSD

Thanks. Just to clarify in case it helps: the DVD iso *was* burned to 
physical _dvd_ medium, not a purported "burn" to usb stick.

If there is some other aspect which regulates and which I'm not picking up 
then I suggest no need to focus further on this one absent others' reports 
-- as noted the BIOS flavour _img_ once unpacked and "burned" (sic) 
to _usb stick_ did in the alternative work.

Reards,
