- Dell XPS 15 L502X 8GB RAM (BIOS only) CD-R physical media

It would be very nice to run /sbin/dmidecode, which is on the .iso,
and report the "BIOS Information" section, such as:
=====
# dmidecode 3.3
Getting SMBIOS data from sysfs.
SMBIOS 2.5 present.
70 structures occupying 2511 bytes.
Table at 0x000F0730.

Handle 0x0000, DMI type 0, 24 bytes

=====
of which the Vendor, Version, and Release Date are the most important.
In the installer, type Ctrl+Alt+F2 to get a TTY, re-direct the output
of dmidecode into a file, and copy the file to a machine with a more-
hospitable environment (using wired ethernet, USB flash memory, etc.)

If there are any errors or unusual behavior, then it also is interesting
to know if the interface for the Floppy disk drive is enabled; but often
this requires searching through BIOS configuration screens.  Sometimes a
CD or DVD can be Read under Floppy emulation, and it is easy for the BIOS
to try this regardless of settings.  Try disabling the Floppy
in the BIOS settings, then re-booting.
