5. How do I create a bootable disk image?
You can use RAMDisk to create a bootable disk image. The following example will
create a disk image that can be used to create a bootable CD-ROM. This simple
example will just load the XP bootstrap, and can be used to start your XP
installation.
To begin with, start RAMDisk with the "Windows Boot Sector" option enabled
(under the "Settings" tab).
Go to the root directory of your XP system disk and do the following (assuming r: is
your RAM disk):
attrib -r -s -h ntldr
copy ntldr r:
attrib +r +s +h ntldr
attrib -r -s -h boot.ini
copy boot.ini r:
attrib +r +s +h boot.ini
attrib -r -s -h ntdetect.com
copy ntdetect.com r:
attrib +r +s +h ntdetect.com
This will install the basic files necessary to bootstrap Windows NT/2000/XP. For
more information, see the Windows NT Workstation 4.0 Resource Kit, p.697. Save
the disk image. You now have an image suitable for creating a bootable CD-ROM.
6. How do I set the drive letter for the RAM disk?
You can modify the drive letter using Windows Disk Management. If you do not use
Windows Disk Management, Windows will automatically assign the next available
drive letter to your RAMDisk. If you want a specific drive letter to appear each time
you run RAMDisk, you will need to save the disk image at some point, and select
"load disk image on startup". Otherwise Windows does not know what drive letter
you have created and will assign the next available drive letter. Of course, selecting
"Unformatted" on the "Settings" tab will create a blank disk with no formatting
information, and therefore no drive letter.
7. Why doesn't the image file timestamp seem to be changing when I have
AutoSave turned on?
RAMDisk keeps track of write activity to the RAM disk, and if there have been no
writes since the last time the disk image was saved the disk image will not be written
out again. This saves on unnecessary hard disk I/O, and can make a big difference if
you have a large disk image that changes infrequently.
8. Can I boot from RAMDisk?
No. Since RAMDisk is a Windows resident program, you can't load Windows from it.
However, you can load a second OS instance from RAMDisk using a multi-session
tool such as VMWare. In fact, RAMDisk is often used with VMWare to increase its
performance.
