This is all very well documented in drivers/platform/x86/thinkpad_acpi.c:

Note especially the

They don't for the older ThinkPads, but they do provide bootable floppy
images which are just as good (don't know if the R50e has a floppy
drive, but you can always convert the floppy image to an el-torito CD or
to a USB stick if necessary).
The only problem with the Lenovo floppies is that they are embedded in a
floppy write utility for DOS, Windows or OS/2. But there is a neat
Linux trick which I used with a Thinkpad T42: Download the "Non-Diskette"
version from Lenovo and unpack it with "cabextract" (from the Debian
package with the same name). The .exe contains a raw bootable floppy
image which can be dd'ed to a floppy or used on an el-torito CD or
whatever. The rest of the files are just the Windows utilites which you
don't need.
