/M Enables read/write multiple using the default value calculated for each
IDE/ATA drive. The default value will be the drive's maximum supported
value or 16, whichever is smaller.
/M= Enables read/write multiple using the specified value (drive_?_value)
for each IDE/ATA drive. Settings for multiple drives are separated by
commas as shown. All values are in decimal and must be a power of two.
Use this option only if you have specific knowledge of your drives'
capabilities.
/P- DISABLE FAST ATA MODE
Description: Disable Fast ATA PIO hardware detection. Prevents the Dynamic Drive
Overlay from trying to detect hardware support for Fast ATA PIO. In rare cases
detection may cause a system, usually one without Fast ATA PIO hardware, to
hang. Use /P- to correct this problem should it occur.
Syntax:
/R= DISABLE READ MULTIPLE
This option controls read multiple on a 'per drive' basis. Read multiple is
enabled by default when /M is used. Write multiple is not affected.
Syntax:
/R={0|1} [,0|1][,0|1] [,0|1]
Option descriptions:
/R= "0" enables read multiple for the drive; "1" disables read multiple for
the drive. Settings for multiple drives are separated by commas as
shown.
See also:
/W= Disable Write Multiple
/M Enable Read/Write Multiple
/S DISABLE SECONDARY SUPPORT
This option prevents the Dynamic Drive Overlay from attempting to control IDE
drives attached to a secondary controller. Use this option if your system BIOS
supports secondary controllers and conflicts with the Dynamic Drive Overlay.
Syntax: /S
/V= VERBOSE MODE
This option controls the amount of information displayed by the Dynamic Drive
Overlay when it is loaded.
Syntax:
/V={0|1|2}
Option descriptions:
/V=0 Quiet mode. Displays only the text "Starting Ontrack...".
/V=1 Default mode. Displays the blue Dynamic Drive Overlay banner and the
"Press SPACEBAR to boot from diskette..." prompt.
/V=2 Verbose mode. Displays all of the above plus configuration information
for all drives controlled by the Dynamic Drive Overlay. This mode is
intended primarily for troubleshooting purposes.
/W= DISABLE WRITE MULTIPLE
This option controls write multiple on a 'per drive' basis. Write multiple
is enabled by default when /M is used. Read multiple is not affected.
Syntax:
/W={0|1} [,0|1] [,0|1] [,0|1]
Option descriptions:
/W= "0" enables write multiple for the drive; "1" disables write multiple for
the drive. Settings for multiple drives are separated by commas as shown.

/R= Disable Read Multiple
/M Enable Read/Write Multiple

Dynamic Drive Overlay Error Messages
ERROR MESSAGES
ERROR LOADING OS
Error 1 loading OS:
This error indicates that the Dynamic Drive Overlay data recorded on the drive
is corrupted. The most common cause of this error is a boot sector
virus.
In most cases, this error can be corrected using the following procedure:
1) Turn your PC off. This will make sure that if there is a virus
it is no longer in memory.
2) Boot the system to a write protected DOS diskette that you KNOW is not virus infected.
You may need to use your DOS installation diskette if you do not have a
bootable DOS diskette that you KNOW is clean.
3) Run Disk Manager, choose Maintenance Options and select
the Upgrade Disk Manager option.
4) Exit Disk Manager and reboot from the hard drive.
5) Check your diskettes for viruses with a virus scanning software package.
Please note that boot sector viruses infect ALL diskettes, not just
bootable diskettes. Most boot sector virus infections occur when you
accidentally start your system with a data diskette (non-bootable) in
the A: drive. By the time the non-system diskette error message is
displayed the virus has already infected the hard drive.
Error 2 loading OS:
This error can occur when the Dynamic Drive Overlay is being read into memory
and most likely indicates a hardware problem.
You may be able to gain access to your data by creating an Ontrack Boot
Diskette. Select Maintenance Options and choose Create Ontrack Boot Diskette.
You can also try Updating the Dynamic Drive Overlay, also under Maintenance
Options.
Error 3 loading OS:
This error can occur on drives using Ontrack Proprietary Format if the partition
table has been corrupted. This error may also indicate a hardware problem.
You may be able to gain access to data by creating an Ontrack Boot Diskette.
Select Maintenance Options, and choose Create Ontrack Boot Diskette.
Then reboot your system using this diskette.
INCOMPATIBLE BIOS TRANSLATION DETECTED
This error is displayed when the Dynamic Drive Overlay is installed on a drive
and a translating BIOS is enabled some time thereafter and the BIOS translation
scheme does not match that used by the Dynamic Drive Overlay.
In most cases, you can correct this by running your systems CMOS setup and
disabling the BIOS translation. If you wish to use BIOS translation rather than
the Dynamic Drive Overlay, back up your data and reinstall the drive with BIOS
translation enabled. Disk Manager will not use the Dynamic Drive Overlay on a
drive supported by BIOS translation.
DYNAMIC DRIVE OVERLAY NOT LOADED
This error indicates that the Dynamic Drive Overlay was unable to find any
compatible hard drives in your system. A hardware failure is the most likely
cause.
NO DRIVES FOUND REQUIRING DRIVER
This error is displayed when booting from an Ontrack Boot Diskette if there are
no drives in the system using the Dynamic Drive Overlay.
If you have drives using the Dynamic Drive Overlay in your system, this error
may stem from a corrupted Master Boot Record(MBR) or a hardware problem.

Identify Data Descriptions
The data shown in this window is the result of issuing the hard drive
selected - an Identify Device command (supported by all current drives).
The results shown here is a summary of the data returned.
The values shown are technical in nature, and a brief description is offered here:
Drive Model: Up to 40 characters, the model name of this drive.
Firmware Revision: Up to 20 characters, the serial number of this drive.
Translated CHS: This is the tranlated Cylinder, Head, and Sector values, and drive size they represent.
LBA Sector Count: The total number of user addressable sectors found on this drive, and the equivalent size.
XBIOS Supported: "YES" indicated that Ontrack's XBIOS is being used to communicate with this drive.
ATA-#: The ATA numbers shown indicate the AT Attachment standard that determine the physical, electrical, transport, and command protocols that this hard drive has been designed to comply with. The higher the number, typically the newer the drive and higher level of standards this drive supports. Values shown from ATA-2 to ATA-5 are accurate, ATA-6 and higher are based on flags reserved for ATA 6 and higher, but are unconfirmed at this time.
R/W Multiple: "YES" indicates this drive supports Read/Write Multiple commands.
Sectors/Block: The maximum number of sectors per block for Read/Write Multiple commands.
MW DMA Support: The MW DMA (Multi-Word Direct Memory Access) modes supported by this drive.
MW DMA Active: The current MW DMA mode that is active. If your interface does not support UDMA, but does support MW DMA - the MW DMA mode at which the drive is enabled. i.e. If the drive supports UDMA 5, but the interface only supports MW DMA 2 - then this field will show a 2 and UDMA (below) will show 'None'.
MW DMA Cycle Time: The cycle time, in nanoseconds recommended by the manufacturer for this drive.
Min Cycle/Word: The minimum time in nanoseconds that this drive supports.
UltraDMA Support: The Ultra DMA modes supported by this drive.
UltraDMA Active: If the interface supports UDMA, the rate at which the drive is enabled.
PIO Mode Support: The data transfer modes supported that are performed by the host processor utilizing PIO register accesses to the Data register and Not DMA.
PIO Cycle Time: If the drive supports IOReady flow control this field shows The minimum transfer time using IOReady, or the minimum transfer time without flow control.
