Network Dropped Packets

I have a Cisco 1720 router. It has a 10/100 nic. On the other end is a Procurve 2810 switch. It has a 10/100/1000 port. I am trying to figure out why the switch is showing RX Drops. No just a few. Like 1 every second at least. There is moderate traffic over the connection. I have check to make sure both were set to 100FD and even tried 100HD but, the problem still persist. I have turn on Flow Control in the switch but nothing changes. Is it possible that the router is to old and can't handle being connected to this new of a switch? Is that possible? I am looking for way to track down the cause. I have tried everything I can think of.

1) swap the ethernet cable from the router to the switch
2) the ethernet on the router and the port on the switch must be set the same (either auto or hardcoded speed and duplex matching)
3) if you have a lot of data coming in on the router ethernet interface, you may need to increase the hold-queue in.  If the default is, for example, 75, change it to 150

I updated the software on the switch and then was able to change the buffer. This seems to have resolved the problem. Thanks.
