No additional drivers are required for Windows 98, 2000, Me or XP.

 

3.Can my PC boot from the LS-120?

The Mitsubishi LS-120 flexible disk drive may be configured as a bootable drive provided that both the operating system and motherboard support it as a bootable device.

BIOS versions that support LS-120 booting are:

  • Phoenix from v6.0
  • AMI from v6.26
  • Award: *Availability depends upon the motherboard manufacturer

Operating systems that recognise the LS-120 as a bootable drive are:

  • Windows 95 OSR2, OSR2.1, OSR2.5 (ie. versions B or C)
  • Windows 98, Me, 2000, XP
  • Windows NT 3.51 with Service Pack 5
  • Windows NT 4.0
  • OS/2 Warp versions 3 or 4

MS-DOS and the first release of Windows 95 do not support booting from the LS-120.

 

4.How can I clean the heads of my LS-120 drive?

Do not use any type of cleaning diskette in the LS120 unless it is marked with the LS120 logo and has documentation explicitly stating that it functions with the LS120. The use of other types of head cleaning diskette may seriously damage the LS-120 drive, voiding warranty.

A head cleaning kit for LS-120 SuperDisk drives is now available from Imation. It should be used when read and write errors regularly occur. Please follow the instructions included with the kit when using it.  

 

5.Can I use a normal head-cleaning disk to clean my LS-120 disk drive?

No, the LS-120 disk drive's heads are more sensitive than those of a standard 3.5" floppy disk drive and may be damaged by most types of cleaning disk. Make sure that you only use cleaning disks that are marked as suitable for use with LS-120 or SuperDisk drives.

A head cleaning kit, manufactured by Imation, is now available.  It should be used when read and write errors regularly occur. Please follow the instructions included with the kit when using it.

 

6.I am having problems installing Windows NT from my LS-120, how can I do this?

When you boot from the Windows NT installation disks, the following error message may be displayed when disk 2 is inserted:

Stop 0x0000007B Inaccessible Boot Device (0xFF109C50, 0x00000000, 0x00000000, 0x00000000)

An error may also occur if you attempt to create a set of installation disks.

Microsoft advise that Windows NT Workstation should be installed using the /b switch, bypassing the need for the installation disks. Refer to Microsoft article Q172773 on their support page for more details.

 

7.Where can I get an LS-120 device driver for OS/2 Warp?

A device driver for OS/2 Warp versions 3 and 4 is available from IBM's support site at:

8.The LS-120 drive is not recognised by Windows NT 4.0, how can I fix this?

This problem can occur where all other disk drives and CD-ROM drives in the system are SCSI devices. To enable the ATAPI device driver, open the Control Panel and double-click Devices. Scroll down the list to find the atapi device and check that it has started. If it has not started, click Startup and change the Startup Type to Boot. Restart the system to enable the ATAPI device driver.
