DATA BUS SPEED NOTES |
|
On some systems the data bus timing is not truly IBM PC/AT compatible. If the card is not initializing, Changing the data bus speed from 'Normal' to 'Fast' may allow the card to operate properly. To change the data bus speed you must use the ICRCNFIG utility that comes with the card. |
