Question	Answer
How do I remove	1	Double-click the 3Com icon to start the 3Com NIC
the 3Com icon from		Diagnostics program.

Which PCI slot	3Com PCI NICs, such as the OfficeConnect NIC, are
should I use for my	designed to work in any bus-mastering PCI slot, preferably
OfficeConnect NIC?	slot 1. Normally, slot 1 is marked on the PC motherboard
	and is located closest to the computer power supply.
	Avoid any PCI slot next to an ISA slot. This is often a
	shared slot and does not support bus mastering. The
	NICs perform best in those slots that support
	bus-mastering data transfers.
	Some PCs have three types of expansion slots: PCI, ISA,
	and EISA. PCI slots are usually white and shorter than the
	other expansion slots (see Figure 3 in Chapter 2). ISA slots
	are usually black. EISA slots are usually brown, and are as
	long as ISA slots. If you’re not sure what type of expansion
	slots your PC has, see your PC documentation for details.
	Also refer to your PC manual for information on which
	slots support bus-mastering data transfers.
Do I have to configure	PCI is a self-configuring bus architecture. Most of the
the OfficeConnect NIC?	time you only need to install the NIC in your PC; PCI does
	the rest. However, on some PCI computers, you may be
	required to configure the computer’s BIOS manually after
	installing your PCI NIC. Refer to your PC documentation
	for more information about your PC’s BIOS.
What interrupts	You should avoid using any interrupts used by ISA/EISA
should I avoid?	boards that do not properly support shared interrupts
	(level-triggered). If you don’t know or aren’t sure whether
	other devices or adapters in your PC support shared
	interrupts, then avoid using them.
	Avoid using the same interrupt as your local hard drive
	(normally IRQ 14 for IDE drives and IRQ 11 for most SCSI
	host adapters), because not all hard drives support shared
	interrupts at this time. Avoid using 9 because it cascades
	with 2.
Does the OfficeConnect	Yes, the OfficeConnect NIC supports full-duplex operation
NIC support	at 10 Mbps and 100 Mbps.
full-duplex?	Full-duplex is the ability of a device or line to transmit data
	simultaneously in both directions (the PC is sending and
	receiving data at the same time).
