Sadly, this DCL X4 is some local crappy "brand" without a proper place
for downloading the BIOS files. So, you could either contact DCL
directly (while this company still exists) and ask them for a BIOS
image. Or find someone else with the same laptop and ask them to dump
their BIOS. Searching by the BIOS version (NX300KSZ.05), I've found at
least one person -
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1877009 , could
contact them directly at launchpad and ask for help.
