Notes:
1. Low-power versions only. Reserved on standard-power version.
2. Extended functions 8000_0002h, 8000_0003h, and 8000_0004h each return part of the processor name string. Some AMD-K6-2E pro-
cessors may have the following name string: function 8000_0002h, ECX = 322D_296Dh and EDX = 6F72_5020h, and function
8000_0003h, EAX = 7373_6563h and EBX = 0000_726Fh.
3. Extended functions 8000_0002h, 8000_0003h, and 8000_0004h each return part of the processor name string. Some AMD-K6-IIIE+
processors may have the following name string: function 8000_0002h, ECX = 492D_296Dh and EDX = 5020_4949h, and function
8000_0003h, EAX = 6563_6F72h and EBX = 726F_7373h.
4. Extended function 8000_0006h returns the processor L2 cache information. For the AMD-K6-2E+ processor Model D, ECX =
0080_4220h. For the AMD-K6-IIIE+ processor Model D, ECX = 0100_4220h.
