Vendor String
CPUID function eax=$0
Returned in ebx,edx,ecx

This function returns the ID string of the manufacturer of the CPU. A table of manufacturers can be found in Chapter #5 of the guide. The string should always be exactly 12 characters in length. The first four characters are found in ebx, the next four in edx, and the final four in ecx.

See the sample CPU vendor program for an example of how to implement this code.
