| 36 | to stop the timer if the process managing it closes the file |

| 393 | single board computers, namely the 6010 PII based computer. |
| 394 | It may well work with other cards. It reads port 0x443 to enable |
| 395 | and re-set the watchdog timer, and reads port 0x45 to disable |
| 396 | the watchdog. If you have a card that behave in similar ways, |
| 397 | you can probably make this driver work with your card as well. |

| 752 | Saying Y here and creating a character special file /dev/temperature |
| 753 | with major number 10 and minor number 131 ("man mknod") will give |
| 754 | you a thermometer inside your computer: reading from |
| 755 | /dev/temperature yields one byte, the temperature in degrees |
| 756 | Fahrenheit. This works only if you have a PCI-WDT501 watchdog board |
| 757 | installed. |
| 758 | |
| 759 | If you want to enable the Fan Tachometer on the PCI-WDT501, then you |
| 760 | can do this via the tachometer parameter. Only do this if you have a |
| 761 | fan tachometer actually set up. |

| 774 | This is the driver for the Berkshire Products USB-PC Watchdog card. |
| 775 | This card simply watches your kernel to make sure it doesn't freeze, |
| 776 | and if it does, it reboots your computer after a certain amount of |
| 777 | time. The card can also monitor the internal temperature of the PC. |
