Problem in booting up with external CDROM support(via USB)

Hi,

I have a laptop installed with WinXP on the NTFS partition, with external CDROM via USB. Also, I have a Win98 boot disk in which I use Nero to burn to CD i.e. a Win98 bootup CD. I've also included some files/programs inside the CD.

My intention : After inserting my Win98 bootup CD in my external CDROM(via USB), I try to restart my laptop hoping to boot in Win98 with CDROM support.

Result : I can boot into Win98, but I can't have the CDROM drive. Error message indicate driver not found. This means I can't access to files/programs I've loaded into the CD(together with the bootup).

Actually, what I'm trying to do here is to create an image of my current C: NTFS partition with Ghost2003. I've been using the above method for my other PCs with ATAPI-CD-ROM and I dun have problem with that. But now my CDROM is external via USB and thus I have problem in creating the C: image of my laptop.

Would appreciate it if anyone can provide solution to the problem of my above method, or advice on another better way to create the image of my C: NTFS partition.

Thanks in advance

After a second cup of coffe it dawns on me that the issue is USB support under DOS; the Windows 98 boot disk is nothing more than a DOS boot disk.

This is a problem as DOS not natively support USB devices. You could investigate thread616-682740 or the more contemporary:
There is the additional problem that DOS (and Windows 98) does not natively support the NTFS partitions of your hard disk drive. Make sure your version of Ghost is able to do so.

I would upgrade Ghost to Version 9.0, as it would resolve all of these problems as it operates under Windows during any image creation or backup and under its own steam while doing a restore.
 
Hi,
Thanks for the info. But still having problem with the Win98SE boot. Didn't manage to get the USB driver from the hyperlinks either. Would appreciate it if you could help to create a DOS bootup disk image that can read the external CDROM, as well as the NTFS partition if possible.

Thank you very much

Jason,
Even though you are booting with your CD, you are still required to load device drivers for your CD Rom to allow access to the drive.
This will let you read/execute the contents on your CD.
If you have a bootable floppy disc that loads device drivers for your CD Rom, you can use the commands/file references (from the autoexec.bat and config.sys) and device drivers from the floppy disc for your bootable CD.
Check out the following link at "Bootdisk.com" for more information:

Good luck and post when you have your best solution!

"To access your CD from DOS, you also need at least one other file. Windows provides two generic CD Rom drivers -- Oakcdrom.sys on newer versions of Windows and Nec_ide.sys on some older versions. One of these will probably work with your CD ROM: search for those files on your system (or on one of the boot floppies mentioned above) and copy it to the new boot floppy. In my case, I use Nec_ide.sys."




NTFSDOS.EXE is a file system driver for DOS/Windows
that is able to recognize and mount NTFS drives for transparent access. It makes NTFS drives appear indistinguishable from standard FAT drives, providing the ability to navigate, view and execute programs on them from DOS or from Windows, including from the Windows 3.1 File
Manager and Windows 95 Explorer.

The latest version of NTFSDOS can be found at



A full read/write version of NTFSDOS is available in the form of NTFSDOS Professional, available for purchase online at Winternals Software -
 
The issue I believe is that the device is USB, not that it is a CD Rom.

Moreover, it is essentially a DOS boot we are talking about, and it is not native for DOS to support USB devices in pure DOS mode.
