SWIFT SM FREQUENTLY ASKED QUESTIONS
Topics:
1. Parallel Port Recognition Issues
2. Miniport Driver (MPD) Loading Problems
3. Daisy Chaining and Swift SM Devices
4. General Checks and Tips on Improving Overall Performance
1. Parallel Port Recognition Issues
The system has an EPP parallel port, but the MPD does not initialize in EPP resulting
in lower than expected speed.
Solution:
The Swift SM MPD will initialise in EPP only for parallel port bases set to 378h
and 278h. If the parallel port to which the Swift SM Device is connected is configured
for 3BCh, the MPD will not initialise in EPP.
Check the port base setting for the parallel port to which the Swift SM Device is
connected in the following way:
From the Device Manager, expand the Ports(LPT and COM) item.
Click on the LPT port, Click on Properties, Select the Resources tab and the port base
setting will be displayed. Change it to 378h or 278h and re-boot the system.
Check that the configuration for the parallel port in the systems CMOS setting also
reflects the same change that has been made in the Device Manager.
Check if the parallel port mode setting in the CMOS is set to EPP.
2. Miniport Driver (MPD) Loading Problems
The system crashes after installing the Swift SM MPD.
Solution:
a. Disconnect the Swift SM Device and bring up the system.
b. In the Device Manager, expand the SCSI adapters item, click on the CARDport Swift SM
entry, click on Properties, select the Settings tab,
c. Type "/DE",
d. Save and re-boot the system after connecting the Swift SM Device.
If this does not work:
Repeat steps a and b.
c. Type "/R2 /W2 /DI"
d. Save and re-boot the system after connecting the Swift SM Device.
Configuration clashes often lead to problems that crash the system or prevent the
Swift SM MPD from loading successfully. Check that the other devices installed in
the system are not configured to use the same port base and IRQ values.
A typical example is Sound Cards which are popularly configured to use IRQ 7. Refer
to section 6. for more information on this topic.
3. Daisy Chaining and Swift SM Devices
Swift CF and Swift SM devices may be Daisy Chained using Windows 95 & Windows 98.
First, power off, connect the Swift SM then restart and install the Swift SM. Then
power off, connect the Swift CF in series to the Swift SM, connect both power
supplies, then restart and install the Swift SM. The printer may also be connected
in series.
Multiple Swift SM devices Daisy Chaining is not currently supported, in Windows NT4.0.
4. General Checks and Tips on Improving Overall Performance
Ensure that all cable connections are secure.
Ensure that the CMOS setting configuration for the parallel port and the setting in
the Device Manager are the same.
Ensure that there are no Port Base and IRQ clashes with other installed devices such
as Sound Cards.
If the parallel port supports EPP, ensure that the parallel port mode in the system
CMOS is set for EPP.
To step up the system performance, in the Control Panel, select System, select the
Performance tab, click on File System, ensure that the Performance is set to Full.
Select the Trouble Shooting tab and ensure that the Write Behind Cache is enabled.
These are usually the default settings.
The Swift SM MPDs are programmed to give maximum performance for the following
parallel port Port Base and IRQ combinations:
378h and 3BCh and IRQ 7
278h and IRQ 5
Port Base and IRQ combinations other than these are likely to slow down the
performance.
If your systems parallel port is configured differently, for e.g., 378h and IRQ 5,
the IRQ value must be explicitly specified to the MPD as follows:
From the Control Panel, select System, click on Device Manager, expand the SCSI
Controllers item, click on the CARDport Swift SM entry, click on Properties,
click on the Settings tab and type:
IRQ=5
Save the settings and re-boot the system.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
