  The Watchdog Driver will automatically find your watchdog card, and will
  attach a running driver for use with that card.  After the watchdog
- drivers have initialized, you can then talk to the card using the PC
- Watchdog program, available from http://ftp.bitgate.com/pcwd/.
+ drivers have initialized, you can then talk to the card using a PC
+ Watchdog program.
 
  I suggest putting a "watchdog -d" before the beginning of an fsck, and
  a "watchdog -e -t 1" immediately after the end of an fsck.  (Remember
  to run the program with an "&" to run it in the background!)
 
  If you want to write a program to be compatible with the PC Watchdog
- driver, simply do the following:
