Dear Sir/Madam,
The following should help you resolve the problem you are experiencing.
Subject: Using the UDMAUPDT.EXE Utility
Summary: To identify and resolve potential symptoms that may arise when
using DiamondMax UDMA/66, UDMA 100 (and newer) hard drives on older UDMA Motherboards with an older, Core BIOS.
----------------------------------------------------------------------------
---
Overview: Some older Ultra DMA motherboards with older BIOS' (revision
date 10/28/98 and older) have exhibited compatibility issues with Ultra
DMA/66/100 drives. The symptom manifests itself as a system hangs at boot,
and
performance problems. On some motherboards the system does not properly
check the
UDMA setting returned by the drive. This results in the motherboard
attempting
to set itself up in Ultra DMA mode 4 - a mode that it does not support.
These
issues arise because of a bug in the system's BIOS, NOT a problem with the
Maxtor
hard drive. Some System's will also have performance problems due to the
controller chipset.
To eliminate this problem, Maxtor has developed the UDMAUPDT.EXE utility.
This
program is designed to change (update) the UDMA Mode that the drive reports
to
ANY UDMA Mode (0-5). This file can be downloaded from Maxtor's Website. It
is
contained in the file named 100UPDT.EXE.
NOTE: 100UPDT.EXE is a self-extracting file containing:
· UDMAUPDT.EXE - Utility for Changing the UDMA settings on Maxtor UDMA
66/100 hard drives
· CHIPSET.DRV - Driver Database File
· UDMAUPDT.TXT - This file
Maxtor recommends that you copy 100UPDT.EXE to a formatted, 3.5-inch floppy
diskette. Place the diskette containing 100UPDT.EXE in the "A:" drive, at
the
"A:" prompt type "100UPDT" to extract the files. The files must be
extracted in order to execute UDMAUPDT.EXE.
NOTE: This utility should ONLY be used if:
· There is a DiamondMax 6800 (or newer) hard drive physically installed in
the system.
· The hard drive is attached to an IDE Interface port on the motherboard.
· The IDE interface that the drive is connected to does not support Ultra
DMA 66/100.
Contact the motherboard or the controller card manufacturer if the interface
is supposed to support Ultra DMA 66/100 and if problems still persist.
PROCEDURE FOR USING UDMAUPDT.EXE:
1. Remove all ATAPI devices (CD-ROM, CD-writer, ZIP, LS-120,etc.)and clean
boot the system to an A: prompt.
2. Insert the diskette containing the UDMAUPDT.EXE.
3. From the A: prompt, type udmaupdt and press [Enter]. The following will
be displayed:
Select Ultra DMA Mode Utility -- Version 2.3
USAGE:
COMMAND LINE INPUTS
/dma: DMA Mode ( 0, 1, 2, 3, 4)
0 - UDMA mode 0 = UDMA 16
1 - UDMA mode 1 = UDMA 25
2 - UDMA mode 2 = UDMA 33
3 - UDMA mode 3 = UDMA 50
4 - UDMA mode 4 = UDMA 66
5 - UDMA mode 5 = UDMA 100
EXAMPLE COMMAND LINE INPUTS -- To set UDMA Mode to UDMA 33
Press any key to continue
You will be returned to an A: prompt after the following is displayed.
4. From the A: prompt, type in UDMAUPDT /dma:n (to set the UDMA mode) and
press [Enter]. The valid values for n are described above. This will
execute the UDMA utility. Information will be displayed on the monitor
indicating if drives are found and the action taken by the utility. In
the example below "(Chip Set)" is the identifying information obtained
from the IDE controller card (if installed) and / or the motherboard of
the computer system.
! IMPORTANT NOTE ! - This utility will set each Maxtor hard drive to the
maximum UDMA mode the drive is capable of operating in or the value of
the command switch, which ever is less (e.g. if the drive is capable of
UDMA 33 (mode 2) and the switch is set to UDMA 66 (mode 4) the drive will
be set to UDMA 33 (mode 2) operations).

NOTE: At least one set of information shown above is displayed. If there
is
an IDE controller card installed in the computer system then a
second
set of information is displayed. The first set displayed is for the
installed IDE Controller Card and the second for the motherboard.
! IMPORTANT ! - If a controller card is installed that utilizes a chipset
not
found in the CHIPSET.DRV file, the card and all devices attached will not
be
seen by this utility. Information for the motherboard will be displayed.
If
all IDE devices are connected to an unknown card the utility will report
that
no drives were found in the system. If this occurs contact Maxtor
Technical
Support and provide information about the controller card so that it can
be
investigated and the utility updated as appropriate.
5. Upon the completion of this utility, the system returns to the "A:"
prompt.

Anche se non hanno centrato il tuo tipo di mobo, io ho specificato tutto :rolleyes: , sembra che il software per cambiare lamodalità DMA esista anche per i D740X e anche secondo maxtor potrebbe risolvere il problema.
