DISKLESS ANGEL Client Configurator Tools – Disk Image Builder

10.1

Disk Image Builder is opened by clicking Build Disk Image under Tools Menu:

10.2

This Window Dialog is used to build disk image file from partition image file. The following is a description of the meaning of the controls of this dialog and the functional keys used:

10.2.1

Input
Input partition image file name

10.2.2

Output
Output disk image file name

10.2.3

Append Image
Append the partition image file to the end of the disk image file, rather than overwrite the disk image file.

10.2.4

Refresh
Refresh the partition list.

10.2.5

Partition List

The list box to the right of the Refresh button is used to display the partition list contained in the disk image file. The following shortcuts can be used in this list box after selecting a partition listed:

<DEL>

Delete the selected partition.

<SPACE>

Toggle the active flag for the selected partition. If it is a primary partition, it can be bootable under emulator such as QEMU or bootloaders such as GRUB.

“I” and “i”:

Change file system type for the selected partition.

‘O’ and ‘o’:

Save the selected partition to an external file.

10.2.6

Image Type

This is used to determine the two important disk parameters, sectors per track and number of heads. “Default” value is 63, 255, “Cdrom” value is 32, 64. “Custom” means you want to enter these two values manually.

10.2.7

File System

File system id for the input partition image file. “Auto” means auto detect file system id. In this mode, the id for FAT16 is 6, and the id for FAT32 is 11. “Lba mode” means using id 14 for FAT16 and id 12 for FAT32. “FAT16 small” means using id 4 for FAT16. If none of the predefined settings is suitable, one can use “Custom” and enter the appropriate id.

Lba mode is suitable for building bootable disk image file used under QEMU, while Auto mode is good for loading bootable disk image file under GRUB.

Please go to http://windrv.net for downloading two LGPL utilities, WinQEMU and WinGRUB that help one using QEMU and GRUB under Windows.

10.3

To be able to boot the disk image file under emulators such as QEMU or by bootloaders such as GRUB, the disk image file should contain as least one active primary partition. The disk image file should also contain a valid Master Boot Record [MBR] and a valid Boot Sector [BS] in the active primary partition. To help users to install MBR and BS for making a bootable disk image file, one can use MBR/BS Manager to be introduced in Chapter Eleven.
