Known Problems and Limitations

If data corruption errors occur while an NE2000 or NE2000plus card is installed,

check the bus speed that is set on the card. (This is a conﬁgurable option on some

compatible cards.) Some cards may not run reliably at 16 MHz and must be

conﬁgured to run at 8 MHz.

Some NE2000 and NE2000plus compatibles may misidentify slot width or may not

work with all mode or jumper settings. For example, some NE2000plus

compatibles may only work in both data modes (I/O and shared memory),

depending on the system conﬁguration. Try a different bus slot if the card

misdetects a 16-bit slot for an 8-bit slot. For NE2000plus compatibles, try both data

modes by setting the jumpers or using the DOS conﬁguration program.

If the NE2000 card is not recognized by the Solaris operating environment, it’s

possible the compatible does not sufﬁciently resemble the NE2000 hardware.

Improper conﬁguration setup may also cause this failure.

If the system hangs or the NE2000 card is not recognized by the Solaris software, it

may be necessary to reset the bus speed or I/O recovery time (which may be

settable in the system BIOS). General bus noise may also affect the behavior of

certain NE2000 compatibles; try swapping devices into different slots until the

card functions satisfactorily.

If the system hangs after booting with an NE2000 or NE2000plus card installed

but it doesn’t hang if you remove the card, check that:

The NE2000 or NE2000plus card has been jumpered for 16-bit operation and

has been placed in a 16-bit slot. Some cards misdetect slot type.

The NE2000 or NE2000plus compatible is recognized. If it isn’t, replace the

card.
