Using GHOST with NVIDIA RAID

Problem

GHOST can interface with hard disk controllers by accessing the appropriate memory and hardware locations directly. However, in doing so, this can bypass the

RAID enhancements that are provided by the system

BIOS. The system BIOS understands the underlying disk and RAID array structures and formats. In order to properly use GHOST to interact with a RAID volume, the user should ensure that the tool is operating in a mode where it does not talk directly to the hardware resources, but rather communicates using the system BIOS.

Solution

In order to GHOST in a RAID volume, the user must:

• Disable the GHOST Direct Disk Access

• Force it to rely on Extended INT13 to access the disk

To set GHOST to use Extended Interrupt 13h(INT13)access-

a. Start GHOST from the DOS prompt. (Not the Windows

Command Prompt session)

b. Select the “Options” (Alt+O) menu

c. Scroll to the “HDD ACCESS” Tab

d. Select the “Use Extended Interrupt 13h disk access”(Alt+E)

e. Select the “Disable direct IDE access support”(Alt+B)

f. Select the “Disable direct ASPI/SCSI access support”(Alt+B)

g. Press (Alt+A) to activate the “Accept” button to use the

new settings

h. Proceed to run GHOST as normal

58

These steps will then allow the user to ue GHOST to copy the disk image through the RAID array.

Note: Typically, disk cloning software accelerates data

transfer through direct disk access, which also

allows for overlapping read and write calls, further

accelerating the process. Because INT13 calls

cannot “overlap”, read and write operations must

be performed in series, which causes the disk

cloning process to perform slower when RAID is

enabled.
