+
+I am making this a general-purpose userland flash burner -- RGM
+
+Earlier notes from Ollie:
+
+Here is some utilities for using/programming flash ROM on SiS 630/950 M/Bs
+
+ 1. flash_on, turnning on the flash writer enable for 630/950 M/Bs,
+ you have to run this before load DoC drivers.
+
+ 2. flash_rom, use your 630/950 M/Bs as a flash programmer for some
+ flash parts. This utility is made as modular as possible. If
+ you find your flash part is not supported, you can add a driver
+ your own. Or sending me the data sheet.
