The code multiplies by 10, which would be decihertz. Hecto is 100.
1564 /* As far as I can tell, these are in hecto Hertz (i.e. e2).
1565 * Yes, this is weird. */
1566 tmp = BIOS16(offset + 4);
1567 printf("Maximum frequency: %dHz\n", tmp * 10);
On top of it, I wrote it wrong myself. D'oh. I guess I meant "decahertz".
This is filed against avivo, which is dead. Closing as such.
