>Description:

	I swapped out a Linksys Ether 16 (ISA) LAN Card and replaced it with a
	Linksys Combo EtherPCI LAN Card on my FreeBSD 2.1.7 system, and noticed
	that the throughput speed on network file transfers went *down* from about
	10 Mbits/s to about 5 Mbits/s; once I put back the 16-bit card throughput
	speed went right back up to 10 Mbit/s.

	Could the slow-down be in the driver for the PCI Ether card???

	Just wondering; I am just surprized that a 32-bit (and twice as expensive)
	ethernet card runs *half* the speed of a 16-bit card; both cards are
	made by Linksys.

	Also, swapping out the PCI Ether card got rid of many "stray irq 15" messages
	appearing during boot-up; is there a connection?

This pretty much looks like PCI BIOS misconfiguration, interrupt problems, 
or maybe even hardware problems.
