In searching for information about the Alix 1.c bios upgrade I'd like to do I came across mention of flashrom, a command line utility which can do firmware flashing for a lot of systems right from the commandline. No more long downtimes due to being busy with bootable floppies, cd's, usb sticks or slow update programs.

Initially the program gave a warning on ritchie, but with one "I am sure what I am doing" option:
root@ritchie:~# flashrom --programmer=internal:laptop=this_is_not_a_laptop -r oldbios.bin
flashrom v0.9.6.1-r1563 on Linux 3.12-1-486 (i586)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
========================================================================
WARNING! You may be running flashrom on an unsupported laptop. We could
not detect this for sure because your vendor has not setup the SMBIOS
tables correctly. You can enforce execution by adding
'-p internal:laptop=this_is_not_a_laptop' to the command line, but
please read the following warning if you are not sure.

Laptops, notebooks and netbooks are difficult to support and we
recommend to use the vendor flashing utility. The embedded controller
(EC) in these machines often interacts badly with flashing.
See http://www.flashrom.org/Laptops for details.

If flash is shared with the EC, erase is guaranteed to brick your laptop
and write may brick your laptop.
Read and probe may irritate your EC and cause fan failure, backlight
failure and sudden poweroff.
You have been warned.
========================================================================
Proceeding anyway because user forced us to.
Found chipset "AMD CS5536". Enabling flash write... OK.
WARNING: unexpected second chipset match: "AMD CS5536"
ignoring, please report lspci and board URL to flashrom@flashrom.org
with 'CHIPSET: your board name' in the subject line.
Found SST flash chip "SST49LF040B" (512 kB, LPC) at physical address 0xfff80000.
Reading flash... done.
Checksums for the saved bios file match with the bios image I have from the last upgrade.
