1) now that I have a bootable DOS usb-key (thanks for that image by the way, every other FreeDOS style setup I've tried has thrown up op-code errors!) and the DOS executable "11CA07D0.EXE" from the samsungpc.com website, can I just boot into a DOS prompt and run that executable; or do I have to use the method described here, i.e. using the extracted files (****B.WPH, ****M.BIN etc...) and running UPBIOS and UPMICOM?
Yes, you can use directly the official samsung updater for DOS.
2) if the latter method has to be used, is it ok to use the files for the NC10, contained in "11CA_dos.zip" even though I'm using an N110?
No, those files are for NC10 only. Anyway, just go with the official samsung updater.
