Chase AT4, AT8 and AT16 Cards for Microsoft Xenix

Chase AT cards are currently shipping with version 3.04 and 3.05 firmware. Unfortunately, these releases of firmware will not function under the 3.09 and earlier drivers supplied with Apricot Microsoft Xenix.

The implications of this are as follows:-

Where a faulty card is being exchanged on a Microsoft Xenix system, the firmware ROMs should be exchanged between the old and the new cards prior to installation.

Where an existing customer wishes to upgrade the number of ports on his system, old versions of the firmware (e.g. 3.02) will have to be obtained first. If this is not possible, it may be necessary for the customer to upgrade to SCO Xenix 386, so the latest Chase drivers may be incorporated.
