Z-NOTEFLEX COM1 disable utility

We have posted a utility (dsblcom1.zip) on the BBS, it can be used ONLY on the Z-NOTEFLEX to disable the external serial port. If used before VMI Cardware, you will be able to use a PCMCIA card as com1. Also, it can be used to free up IRQ4 if you need an extra interrupt.

See below dsblcom1.txt file (attached):

DSBLCOM1.SYS Release 1.0 Notes

This version of dsblcom1.sys will ONLY work on the Z-NoteFlex.


Use this driver to disable your external serial port (com1) to free up I/O 3f8-3ff and IRQ 4. This will allow VMI Cardware to support two PCMCIA modems, one at COM1 (default I/O 3f8-3ff, IRQ 4), the second at COM2 (default I/O 2f8-2ff, IRQ 3). This may also be helpful when using the FlexShow if you require an additional IRQ (4).


Copy the provided driver (dsblcom1.sys) to your C:\CARDWARE directory.


Add this statement to your config.sys BEFORE the VMI Cardware drivers.


then follows the VMI Cardware drivers


Additional notes:

This version of dsblcom1.sys will ONLY work on the Z-NOTEFLEX.

Z-NOTEFLEX ZINFO File / Memory Upgrades

Please note that we have added ZINFO.EXE to the PORTABLES section of the Zenith Data Systems BBS available to our customers. It is for use on the Z-NoteFlex ONLY.

Make sure the customer presses F5 during the boot process to bypass CONFIG.SYS and AUTOEXEC.BAT files prior to executing this file.

Here is a sample of the display:

Highlighted are the two main information lines. The first is the BIOS version, the second is the Boot Block version.

In order for the Z-NOTEFLEX to properly configure some third-party two-bank simms, the Boot Block version MUST be V1.4 or LATER. If it is not, the customer has to download 3681-00.EXE from our BBS to upgrade to V1.4 of the Boot Block code.

In order for the 3681-00.EXE to upgrade the Boot Block to V1.4, the customer must be at or BELOW version 1.1B of the BIOS version. If the customer is at a version LATER, such as 1.1E, you must first have the customer downgrade their BIOS to 1.1B or earlier, then upgrade the Boot Block via 3681-00.EXE, and finally upgrade the BIOS version to the latest version, 1.1F (currently).
