=== PRODUCT UPDATE NOTICE - PCASIM V1.00.01.07 ===

March 10, 2000 - PCAUSA releases update V1.00.01.07 to the PCASIM NDIS
Intermediate (IM) driver samples for Windows NT 4.0.


= Bug Fixes =

1.) Fixed bug in receive handling for legacy adapters such as the 3Com
3C509. The bug was associated with an incorrect call to NdisTransferData
when a legacy adapter did not indicate a complete packet to the receive
handler.

2.) This release fixes an ASSERT was generated when PCASIM is started under
CHECKED build. The ASSERT was caused when NdisEqualString is called at IRQL
DISPATCH_LEVEL because it was within a SpinLock; the function should only be
called at IRQL PASSIVE_LEVEL.

The details of the PCASIM V1.00.01.07 update (and prior updates) can be

the fix to Bug No. 1 can be found in the PCAUSA Knowledge Base article
KB01210001, "Bug In Receive Handling For Legacy Adapters". This information
should be sufficient for you to make changes to your own code.
