If you are using removable media (for example a SD card on an
UltraSatan) the program also displays a window indicating that a
removable drive has been formatted and the maximum number of
bytes for the logical sectors. Write down this value as you will
need it to set the driver parameters and click OK.
A new window is presented to indicate that the partitions have
changed and offers you to reboot the computer, click OK. During
reboot the ICD driver should display all the drives connected and
a list of all the partitions found.
The write partition only command allows rewriting only the MBR of the drive. This command can be
used if the MBR of the drive have been corrupted and you are trying to save the data already existing
on the drive. You should make sure that you have not changed the size of any partition when you use
this command.
The rebuild one partition only command reinitializes a specific partition (rebuild boot sector, FAT,
and the Root Directory). The program will ask you which partition you want to rebuild. This command
can be useful if you have only one partition corrupted and you want to keep the data in the other
partitions. You should make sure that you have not changed the size of any partition when you use
this command.
4.6.2 Enabling and Disabling Auto boot
Auto boot allows your system to boot directly from the hard drive. This eliminates the need for a boot
floppy diskette and speeds the booting process.
Run the ICD utility program HDUTIL.PRG. This brings you to the main menu.
To enable Auto boot, click Boot from the main
menu. The program default to partition C selected.
If you wish to boot from a partition other than C,
click on that partition. Locate the ICDBOOT.PRG
(usually on floppy drive A) and click on OK. You
will be prompted to be sure that you have the
proper disk in. The boot sector of the partition will
be modified to reflect Auto boot status, and the
ICDBOOT.PRG file will be copied to the root
directory of the boot partition and renamed to
ICDBOOT.SYS. When this is done you will be
returned to the main menu.
If you want to disable Auto boot from hard click
select Floppy as the boot drive and click on OK.
Note: If you wish to boot from floppy only on occasion it is not necessary to disable boot from hard
drive. Simply hold down the CONTROL, SHIFT, and ALTERNATE keys simultaneously while booting the
computer. This will bypass Auto boot temporarily. On some newer computers it is necessary to wait
for the floppy drive access light to come on before pressing these keys.
