MS540 Running Slow

Please be advised that on Apricot machines with the Surepath BIOS (MS540 with Trent Motherboard, will have a model number MMxxxx on a white sticker at the back of the machine), if the machine is interrupted during the boot sequence or fails its post 3 times, it will set the cache to disabled. The machine then runs extremely slow or gives an '062 Boot Failure - Default Configuration Used' error on the next boot.

This can be remedied by enabling cache in SETUP as follows -

  • Let the machine boot into SETUP screen using the prompts necessary.
  • Select 'Advanced Setup' and 'Cache Control'. The cache should be enabled. Escape back to the main menu, save the changes and Exit.
  • The machine will boot then boot into WIN95 as normal.

  • Click on SYSTEM
  • Select MODEM
  • Highlight DATAFLEX PC COMMS and click PROPERTIES
  • Select RESOURCES
  • If MANUAL CONFIGURATION Button is there, then click it. Else goto next step.
  • Remove tick from USE AUTOMATIC SETTINGS
  • Change Basic Configuration to 0004
  • Change IRQ Value to 11
  • Click OK, then OK again.
  • Click CLOSE and restart PC

When PC restarts, Modem will be on Com 3, but using IRQ 11. The yellow exclamation should be gone from Soundblaster, and sound should work in Windows.

Apricots Losing BIOS Settings

Some SCSI cards that are being shipped with scanners which are by default set to address base 140, and are causing problems with Apricot BIOS. After fitting the card all appears to be well, but after a few reboots it knocks out the A: drive in the BIOS. This will keep happening until the SCSI address is changed to something else (normally 340).

MS540 - Unknown PCI

On boot up Win95 detects an unknown PCI card. What its actually finding is the USB adapter. Cure this problem by entering BIOS and disable the USB. Save settings and reset.

Remote Control


Here's the definitive way to reinstall the desired drivers.

  • Using the create system disks utility to create the 2 Logitech Mouse Driver diskettes.
  • Using the SYSTEM PROPERTIES --> Device Manager delete the Logitech PS/2 Mouse and remote control.
  • Reboot the system and let it reinstall the mouse - selecting a standard PS/2 Mouse instead of the Logitech
  • Using ADD/REMOVE PROGRAMS uninstall the Logitech mouse support - named "MouseWare"
  • Use the FIND ... FILES OR FOLDERS function, search for files APREMOTE.* and delete any Application files
  • Reboot the Machine
  • Run the installation program off Disk 1 of the Logitech Driver Disks.

On some later machines the Logitech Mouse software isn't in Create System Disks (only the option for the DOS drivers), in which case you need to create the disks for the Easy Manager software, and use them.

MS5200 - Remote Control Not Working

Remote Control not working, and also the Modem (Supra Express 56k) being detected on Com2 instead of Com3, then the problem is in the BIOS.

Go into Start/Settings/Control Panel/System/Device Manager and remove the Modem. Shutdown the computer and enter the BIOS. Go to Advanced / Peripheral Configuration, select Serial Port B, and change the setting to ASK-IR. Save the settings and exit out of the BIOS. The machine should boot back into Windows and detect the Remote Control and the Modem on Com3.

Windows 98 on Apricot MS Series systems with Remote Control

After installation of the Microsoft Windows 98 upgrade on Apricot MS series systems with remote control, the following message will be seen on startup..


Remote control hardware failed to initialise. To fix the problem, try restarting your system. If the problem persists, please contact your dealer.

The message is being caused because of a conflict between the remote control driver, and the DirectX audio functionality that is an integral part of Windows 98.

Currently there is no upgrade available to eliminate this problem, although one is being investigated. In the mean time, the only way to prevent the message is to do one of the following….

Run the Easy Manager Configuration utility and Disable Easy Manager Or if the other Easy Manager functions are required (without the use of the remote control unit)…

Run REGEDIT and delete the ApricotRemote key that is found in Hkey_Local_Machine\Software\Microsoft\Windows\CurrentVersion\Run.

Note that if option 2 is used and a change is made to the Easy Manager configuration from the Easy Manager Configuration utility, the registry key will need to be deleted again.

The system will operate without making any changes, but the Apremote message will be seen each time the system starts up.

MS540 & HP820cxi

Tries to print but gives an error saying can't communicate with printer. On the MS540, go into the BIOS (F1 on startup), and go to the Devices and I/O Ports section, and change the following settings -

Parallel Port - LPT1
Parallel Port Mode - Bi-Directional
Parallel Port IRQ - 7
Parallel Port DMA - 0

On the newer MS 5200 machines you also need to change Parallel Port Setting from PNP to Auto, and the Parallel Port Mode to Bi-Directional.

MS660 - Graphics Cards

The new MS660 machines have an ATI Mach 64 card in them, as well as a DIAMOND MONSTER 3D card.

If you need to reinstall the Display settings, remove the ATI card as normal from Display Adaptors, and the Diamond card (it's under a different section, I think it's called Diamond).

When you reboot the computer it will install the drivers for the ATI card automatically, but will ask for the driver disk for the Diamond card. This is a CD which should have been supplied with the computer (Labelled Diamond Monster CD).

The drivers are in following directory -


If may also ask for the location of Direct X drivers, these should be in the directory -

Disabling Sensonic Alarm

If you want to disable the sensonic alarm on the MS 540, but can't access the software, then run the program C:\APRICOT\SECURITY\SENSONIC\SETUP.EXE. This process recreates a new Sensonic Plus icon in the APRICOT program group. Opening Sensonic Plus creates the Sensonic icon on the Systray. Double click on this icon and entering the password allows you to disable the alarm.

Apricot MMX and Upgrades

Fitting a Graphics Card or Sound Card upgrade to Apricot MS Series MMX model MW*****-* "Mustang" Motherboard.

When a new graphics card is fitted to this machine it should automatically override the onboard ATI 3D Rage Pro. In the event that it is not disabled automatically the onboard card can be disabled manually by changing jumper J50 to pins 2-3.

When a new soundcard is fitted, the onboard Crystal Audio device can be disabled by changing jumper J80 to pins 2-3. This frees the Interrupts and DMAs used by the original device.

MS600, ATI Rage Pro and Intel AGP

When you go into Device Manager, the ATI Rage Pro, and Intel AGP property sheets will show a conflict, though there will be no conflict icons on the Device Manager list. Despite the message this means that the devices are working perfectly, as the ATI Rage Pro is an Intel AGP device.

MS660 - Microphone

When any form of WAV file is recorded using the supplied microphone the sound level is inadequate on playback no matter how high the various controls are set. This particularly affects the Outgoing Message if the customers record their own message.

The microphone input has no form of amplification in the sound card chips. Therefore the input level will always be too low. The only solution is to use a pre-amplified microphone which must be bought seperately.

MS660 - Speakerphone

Can the built in 'Voice' modem be used to provide a speakerphone facility? The supplied software does not have this facility. More importantly neither does the modem, despite its description. So the answer is no.

HP Colorado Tape Drive

Installing HP Colorado 4/8Gb HP-T4IDE Tape Drive into Lightning based systems

This document explains the procedure for installing a HP Colorado 4/8Gb HP-T4IDE internal IDE tape drive into an Apricot System with a Lightning motherboard running Windows 95.

Tape Drive & Software Installation

Ensure that the systems BIOS is at least 12.03 or greater for Lightning or 10.06 or greater for Spitfire. If the BIOS is lower than 12.03 or 10.06, then upgrade to the latest version before moving onto the next stage.

Connect the Tape Drive as a Slave or Master on the Secondary IDE Controller. Slave if CDROM is fitted, Master if no CDROM is fitted.

When the Tape Drive is connected to the system, start the computer. During Windows 95 startup, an "Unknown Device" will be detected. At this point, click on "Cancel" to abort searching for drivers.

Insert the Colorado Backup CD and install the software. After the software is installed, restart the computer.

During Windows 95 startup, the device "HP-T4IDE" will be detected. In "Device Manager" remove the device:- "Shuttle EPAT External ATAPI Adapter" and restart the computer to complete the procedure.

Recovery Disks Creation

Before attempting to create the Recovery Disks, you need to create the "Colorado Backup for DOS" diskette. This is because the "DOS Real Mode" ATAPI driver needs to be installed onto the Recovery Disks.

Create the "Colorado Backup for DOS" diskette, from the Colorado Backup CD. When you attempt to create the Recovery Disks, you will be prompted for the location of the "Real Mode driver". At this point, insert the "Colorado Backup for DOS" disk, and type A:\ASPI4RAP.SYS and click OK.

You should now be able to complete the disk creation process (creating two recovery disks).

Recovery Disks Creation problems

If you get an error message "An error occurred while attempting to copy file" when trying to create the Recovery Disks, then you need to install Colorado Backup Version 3.21 to cure the problem.

'Illegal Operation' Error When Running Colorado Backup v3.21

After you have installed a HP Colorado 4/8Gb Internal IDE tape drive into a Lightning based system (model prefix MV), when you run Colorado Backup v3.21, it crashes with an 'Illegal Operation' Error message.

This problem is caused by out of date PIIX Bus Master IDE drivers being installed on the computer. To cure the problem you need to de-install the out of date drivers, then install the latest Intel 82371xB INF drivers.

To create an updated driver disk you need to extract the files from within PCIBRDGE.EXE, and to put them on a blank floppy disk.

To De-Install the current PIIX Bus Master IDE Drivers, do the following,

  • Start Windows Explorer, and locate the folder c:\apricot\intel\busmastr.
  • Run the program SETUP.EXE from within the BUSMASTR folder.
  • Click on NEXT, then close down the License read-me file.
  • Click on YES to agree to the license agreement terms.
  • Now click on DE-INSTALL to de-install the current drivers.
  • Follow the prompts then the computer will restart.
  • At "Update Device Driver Wizard", click on NEXT, then FINISH, then YES to restart the computer.

This completes the de-installation of the old PIIX Bus Master drivers. Now that the old PIIX Bus Master Driver has been removed, you can install the latest Intel 82371xB INF Drivers. To perform this task, do the following,

  • Insert the new driver disk into the floppy drive.
  • Click on START, then RUN.
  • Now type A:\SETUP.EXE and press return.
  • Click on NEXT.
  • Click on YES to accept the license agreement terms.
  • Click on NEXT.
  • Click on OK to restart the computer and remove the floppy disk.
  • When the prompt appears to search for the updated "Intel 82371AB/EB PCI Bus Master IDE Controller" driver, click on NEXT, then FINISH
  • When all the devices are found, restart the computer again to complete the process.
  • Colorado Backup should now work ok.
