Installing a Madge Smart 16/4 AT Plus into an IBM ValuePoint Computer

Some customers have experienced difficulty when installing 16-bit token-ring adapters (produced by Madge and other vendors), that use the bus master, shared memory, or programmed I/O methods of data transfer. This document tells you how to install and configure a Madge Smart 16/4 AT Plus Ringnode in an IBM ValuePoint computer. Read it in conjunction with your Ringnode installation guide.

The following IBM ValuePoint computer models are affected:

Other models may also be affected.

The above models are affected because of the difference in the timing value for the Input/Output Channel Ready (IOCHRDY) signal between the ISA and AT specifications. The Madge Ringnode is designed to meet the requirements of the ISA specification, while the IBM ValuePoint is designed to meet the requirements of the AT specification.

Note

IBM have issued a Corrective Service Disk (CSD) with an updated BIOS for 486DX2/66 VP II computers. If you use this CSD when you install a Ringnode in a 486DX2/66 VP II computer, you may not need to follow the procedure described in this TechNote. For more information about this CSD, contact your IBM supplier.

Note

Release 4.2(0) of the Madge Smart LAN Support Software provides improved support for computers that need to use alternate (OTHER) bus-timing. We recommend that you use release 4.2(0) or later of the Madge Smart LAN Support Software.

Table 1 displays the configuration you need to run a Madge Smart 16/4 AT Plus Ringnode in an IBM ValuePoint computer. For example, to run a Smart 16/4 AT Plus Ringnode using SMARTND.OS2 in a ValuePoint computer, do the following:
