HARDCARD 10 - 40 & PREMIUM/286
|
||
|
||
|
||
Plus Development, Inc. presently manufactures three different
|
||
hardcards for IBM compatible systems. Their first product was
|
||
designed to easily add a fixed disk to IBM PC/XT systems and
|
||
compatibles. It was named the Hardcard 10 and had a fixed
|
||
disk capacity of 10MB. Later, as small fixed disk capacity
|
||
improved, they came out with the Hardcard 20 which had a 20MB
|
||
capacity. Their latest product is the Hardcard 40 which is
|
||
designed for both PC/XT and AT type systems and has a capacity
|
||
of 40MB.
|
||
|
||
Hardcard 10
|
||
|
||
This board is designed for PC/XT and compatible systems and
|
||
will not work in AT type systems including the Premium/286.
|
||
There is no 80286 upgrade kit offered for this board.
|
||
|
||
Hardcard 20
|
||
|
||
The original release of this product was designed for PC/XT
|
||
and compatible systems and would not work in AT type 80286
|
||
based systems. However, Plus Development offers an 80286
|
||
upgrade kit that allows the board to work in AT type systems.
|
||
This kit must be installed for the Hardcard 20 to work in the
|
||
Premium/286. Furthermore, the user must follow the upgrade
|
||
kit instruction manual exactly to get the Hardcard to function
|
||
properly in the Premium/286. It is not necessary to include
|
||
the Hardcard during system set up using the AST SETUP utility.
|
||
|
||
Users may obtain the Hardcard 20 80286 Upgrade Kit from most
|
||
larger computer stores. The kit is presently shipping with
|
||
firmware release 4.2.
|
||
|
||
Hardcard 40
|
||
|
||
This product works as shipped in the Premium/286. However, the
|
||
user must follow the installation and set up instructions in
|
||
the Installation and Reference manual exactly. It is not
|
||
necessary to include the Hardcard 40 in the system set up
|
||
using the AST SETUP utility.
|
||
|
||
Caveats
|
||
|
||
1. Due to the fact that the Hardcard requires a full-length 8-
|
||
bit slot and there is only one of these in the Premium/286,
|
||
may cause the user some problems. For example, placing two
|
||
Hardcards in a system and/or if the user is using a non-
|
||
standard display adapter designed for PC/XT systems that
|
||
won't fit into a 16-bit slot. The IBM XT/286 has the same
|
||
problems.
|
||
|
||
2. Neither AST ASTUTE or IBM ADVANCED DIAGNOSTICS for AT
|
||
recognize that a Hardcard is installed in a system. The
|
||
reason for this is because you do not describe the Hardcard
|
||
at set up time.
