Troubleshooting: Promise® FloppyMAX LS-120 Controller
Board User's Guide
Problems and Solutions
| Problem |
Solution |
| The non-ATAPI devices on the FloppyMAX are
in MS-DOS Compatibility Mode in Windows 95a. |
Since Windows 95a does not support the tertiary/quaternary
IDE port addresses that the FloppyMAX uses, any non-ATAPI device
attached to this card will revert to DOS handling methods. |
| Windows 95a does not see the ATAPI device on the FloppyMAX.
|
ATAPI devices require driver support in order for
them to operate. Since Windows 95a does not support the tertiary/quaternary
IDE port addresses that the FloppyMAX uses, any ATAPI device attached
to this card will not be seen by this OS. |
Limitations of the LS-120 Media
- Due to the way MS-Backup for DOS and MS-Backup for Windows
3.1x physically accesses the LS-120 floppy, it is necessary to type in the
complete DOS path to the backup destination rather than to select the drive
from the options list. To do this, enter the Backup menu in MS-Backup,
choose the location to Back up from, then click MS-DOS Drive and
Path and type in the floppy drive letter to back up to and the path (for
example, b:\backup).
- Making a system disk using 120MB media in Windows 3.1x
with File Manager is not possible due to the way Windows 3.1x accesses
the floppy drive. To make a system disk with 120MB media, start a DOS session
in Windows (or exit Windows) and use the DOS format utility.
- Formatting 120MB media in Windows 3.1x with File
Manager returns Probable non-DOS disk error when using chkdsk.exe
to verify the integrity. Scandisk.exe will test the floppy properly.
To make a system disk with 120MB media, start a DOS session in Windows (or
exit Windows) and use the DOS format utility.
- Other limitations of the LS-120 media include the following:
- The diskcopy utility cannot be used in DOS, Windows
3.1x, or Windows 95 due to the large capacity of the media.
- Making a system disk is not possible under Windows
3.1x. In Windows 95, the Create System Disk option from the Startup
Disk tab under Control Panel > Add/Remove Programs
will not work.
- Booting is not possible from DOS or Windows 3.1x.
Interrupting the FloppyMAX
BIOS during Load
With the jumpers on the FloppyMAX set to their default
positions and the LS-120 connected to the FloppyMAX controller board
as a master, perform the following step:
- When booting the computer, right before the FloppyMAX
BIOS attempts to load, hold down BOTH <Shift> keys.
The FloppyMAX will start to display information about what it is detecting
in your system. Please record this information for troubleshooting purposes.
The most common error message resulting from this procedure
is No Interrupt next to the FloppyMAX
port address. This means that the IRQ the FloppyMAX is set to is in use
by another device in the system. Change the IRQ on the FloppyMAX to an
IRQ that is available, or make IRQ 9, 10 or 11 available for use by the FloppyMAX.
|
NOTE: This procedure can be done as long as the
FloppyMAX BIOS is enabled. The jumpers do not have to be set to the defaults,
although troubleshooting is easier if they are.

and disclaimers.
