PREMIUM 486/25 - NOVELL AND IBM TOKEN RING CARDS
|
|||
|
|
|
|||
|
|
|
|||
|
|
Problems have been reported with IBM Token Ring Adapter cards (full length, 8
|
|||
|
|
bit) and Premium 486/25 systems with cache enabled when loading Novell's
|
|||
|
|
IPX.COM. The Token Ring Adapter card fails initialization when executing the
|
|||
|
|
IPX.COM file.
|
|||
|
|
|
|||
|
|
The cause of the problem has been isolated to a software timing loop that
|
|||
|
|
executes too fast for the Token Ring Adapter board to complete its
|
|||
|
|
initialization before the driver times out and produces the error message.
|
|||
|
|
The cause of the problem is the IBM Token Ring Adapters inability to
|
|||
|
|
initialize fast enough on high performance systems such as the Premium
|
|||
|
|
486/25.
|
|||
|
|
|
|||
|
|
The following options are available to customers experiencing the above
|
|||
|
|
problem:
|
|||
|
|
|
|||
|
|
1. Disable and enable the cache using AST's SPEED.COM program prior to
|
|||
|
|
executing IPX.COM by entering the following commands (in the order they
|
|||
|
|
appear) at the DOS prompt:
|
|||
|
|
|
|||
|
|
> SPEED CACHE=DISABLE
|
|||
|
|
> IPX.COM
|
|||
|
|
> NETx
|
|||
|
|
> SPEED CACHE=ENABLE
|
|||
|
|
|
|||
|
|
2. An alternate solution is to update the IBM Token Ring card to a short
|
|||
|
|
card (IBM part number 25f98XX) or a 16/4 (IBM part number 25f73XX) card.
|
|||
|
|
Customer should contact their IBM Dealer for information regarding these
|
|||
|
|
cards.
