- TRUE! From the Adapter Guide for EtherLink II/16 TP and EtherLink II/16:
-
- Table 2-1. Data Mode Transfer Width
-
- Option Jumper Setting
- 8-bit 16-bit
-
- Programmed I/O 8-bit 8-bit
- Shared Memory 8-bit 16-bit
- DMA 8-bit 8-bit
-
- Also, as I've previously noted, to use this card (we have 16 TP) with
- USL's Destiny (SVr4.2) one must put the card in 8-bit mode disable Memory
- Base Address. (I worked with USL's support engineers on this one.) Also,
- your IRQ options are limited to 2, 3, 4 and 5.
