Frequently Asked Questions 3-11
What interrupts
should I avoid?
You should avoid using any interrupts used by ISA/EISA
boards that do not properly support shared interrupts
(level-triggered). If you do not know or are unsure whether
other devices or adapters in your PC support shared
interrupts, then avoid using them.
Avoid using the same interrupt as your local hard disk
(normally IRQ 14 for IDE drives and IRQ 11 for most SCSI
host adapters), because not all hard disks support shared
interrupts at this time.
Avoid using 9 because it cascades with 2.
For Novell NetWare servers, avoid using IRQ 7 or 15. These
IRQs support only nonshared devices and may cause
problems if they are shared between two devices.

Does the 3C900B NIC
support full-duplex?
Yes, the 3C900B NIC supports full-duplex at 10 Mbps.
Why does the 3C900B
NIC install as a “Generic
PCI Ethernet Controller”
under Other Devices in
the Windows 95
Device Manager?
When Windows 95 is installed after the 3C900B NIC has
already been installed, Windows 95 installs the NIC as a
generic PCI Ethernet controller. To work around this
problem, follow these steps:
1 In the Device Manager, double-click Other Devices.
2 Click PCI Ethernet Controller.
3 Click Remove.
4 Restart your PC.
