I may have misconfigured my Coreboot ROM, what did I do wrong?

[Tristan Young]

Today, I internally flashed a Coreboot ROM that I partially built myself to
the motherboard of my ThinkPad T440p. But when I restarted my computer, it
started constantly beeping, and turning it off and on didn't change that
result. Luckily, I fixed it by flashing my previous Coreboot BIOS (SeaBIOS)
to the top 4 MiB chip externally using my Raspberry Pi.

But there are some things that were different in the build configuration
for the newer BIOS, such as trying to use a bootorder file to make SeaBIOS
try to boot from my HDD first instead of my CD/DVD drive, as well as
setting the options to clear the DRAM on each boot. I also didn't use the
cleanbuild option after different build attempts for the newer BIOS.

Should I send my .config file so that you can tell if any of the config
settings or combinations of them that I chose wouldn't work on my specific
model of ThinkPad? And should I also send over an actual 4MiB binary of the
BIOS I flashed that didn't work?
