You can use flashrom to flash your BIOS with these images, all without leaving Linux. I’ve signed them with GPG (keyID 08B6A4AE), and I also provide an MD5 hash which you should check before flashing. You might even want to verify your current BIOS against a provided dump of the same version; this way you can reassure that you have the exact same hardware:

root >>>flashrom -v NC10-07A.rom 
Calibrating delay loop... OK.
No coreboot table found.
Found chipset "Intel ICH7M", enabling flash write... OK.
Found chip "Macronix MX25L1605" (2048 KB) at physical address 0xffe00000.
Flash image seems to be a legacy BIOS. Disabling checks.
Verifying flash... VERIFIED.

It’s probably wise to use flashrom to make a backup dump of the original BIOS of your NC10.
I have an NP-NC10-KA03UK. KA03 is the revision code, printed on the white sticker on the netbooks’ bottom. The roms have been proven to work on other revisions, too — check the comments, or just try it on yours. Please post your revision code if you successfully flashed a revision that hasn’t been posted yet.

One further note: The purchase time in the BIOS will be set to ‘2009/01′ which is when I got mine. But, should the need arise, you may be able to hex-edit the dump and reflash to reflect your true date of purchase (or any date really – you may as well edit it to announce you bought it in August, 1982 if you feel like it). In the 11CA release you’ll find the date at offset 18031E. If that doesn’t work, just flash it with the backup dump you made. You did dump your original BIOS, didn’t you?

Needless to say, these BIOS images are unofficial. But then again, even flashing your bios with the utilities provided by on samsungpc.com void your warranty. You and you alone are responsible for any damages arising from the use or inability to use the images I provide. They are provided ‘as-is’.
