Upgrading Dimension 2400

You cant use DELL XP on a non Dell motherboard.   Unless the board is EXACTLY the same it wont boot.

You will receive a "STOP: 0x0000007B (0xF741B84C,0xC0000034,0x00000000,0x00000000) INACCESSIBLE_BOOT_DEVICE" error message.

After you move the Microsoft Windows XP system (boot) disk to a backup computer, you may receive the following Stop error when you try to start the Windows XP-based backup computer:

STOP: 0x0000007B (0xF741B84C,0xC0000034,0x00000000,0x00000000)

INACCESSIBLE_BOOT_DEVICE

This error may occur if the registry entries and the drivers for the mass storage controller hardware in the backup computer are not installed in Windows XP.

For integrated device electronics (IDE) controllers, there are several different chip sets available, such as Intel, VIA, and Promise. Each chip set has a different Plug-n-Play identifier (PnP-ID).

The PnP-ID information of mass storage controllers for the backup computer must be in the registry before startup so that Windows XP can initialize the correct drivers.

To resolve this error, use the same hardware for the backup computer:

   Replace the problem hardware components in the backup computer with components of the same manufacturer, make, and model as the motherboard in the computer that you are backing up.

   If the system disk is a SCSI disk, use the same make and model of SCSI controller in the new computer.

   If the system disk is an IDE disk, YOU MUST use the same kind of motherboard in the new computer, or a motherboard that has the same kind of IDE chip set and the same PnP-ID as the motherboard in the computer that you are backing up.

You have the option of installing a third party IDE adapter (before you transfer the hard disk) and installing the drivers. When the parts are moved into the new case, move the adapter along with them and connect the hard drive to it for the first boot. Once booted, install the drivers for the new mainboard. After this, the machine can be powered down and the IDE adapter removed.

An alternative is to move the hard drive over and perform an XP "repair install."

When I try this I am am asked to enter an admin password... There never has been an admin password for this system... what can I do to get past this problem?

If it's an admin password in XP, you can use password-cracking software like Ophcrack to recover the passwords.

XP passwords are much easier to crack than those of Vista and 7, because weak encryption is enabled by default.
