| 1461 | * The difference between reset and init is that reset |
| 1462 | * does a hard reset of the chip via index 0x40, bit 7, |
| 1463 | * but init simply forces certain registers to have "sane" |
| 1464 | * values. The hope is that the BIOS has done the right |
| 1465 | * thing (which is why the default is reset=0, init=0), |
| 1466 | * but if not, reset is the hard hammer and init |
| 1467 | * is the soft mallet both of which are trying to whack |
| 1468 | * things into place... |
| 1469 | * NOTE: The data sheet makes a distinction between |
| 1470 | * "power on defaults" and "reset by MR". As far as I can tell, |
| 1471 | * the hard reset puts everything into a power-on state so I'm |
| 1472 | * not sure what "reset by MR" means or how it can happen. |
