Dell Latitude D420 CDROM DOS Drive issue
May 24^th, 2007 at 12:56pm

Ok I desperately need some help here guys or I risk loosing my sanity...

I have a Dell Latitude D420 with a DVD/CDR drive in the docking bay. We (no laughing) use Ghost 7.5 to do all our imaging however we have a few users in a remote site that need to re-image laptops and I want to get an image on a DVD, send it out and wham job done...

I have followed the "Guide to Creating Bootable CD/DVD's without A:\ Floppy Drive" to a T however the optical drive never gets recognised and therefore not mounted. I have tried swapping the oakcdrom.sys with gcdrom.sys yet this has not helped. The process carries on running and boots into ghost ok but thats where it all ends as the really important .gho file is on the damnable DVD media!!!

GOSH.. Sad

I am sure this is a no brainer but it is late, I am tired and have been at this for far too long today so any suggestions would be greatly appreciated...

Do any other bootable optical disks work?

The installation CD for Ghost 7.5 should be bootable--loads a large variety of CD-ROM drivers.

The Win98oem or WinME boot floppy loads a variety of CD-ROM drivers--their files could be used to create the bootable sector of an optical disc: Boot Disks

You might have to research your CD-ROM drive to determine if it needs a special DOS driver to replace *oakcdrom.sys*.

Thanks for your reply.

The drive can boot from other optical media, I tried using the WinME boot disk option this morning however I get the message:

"Device driver not found: 'MSCD001'
No valid CDROM device drivers selected"

Back to the drawing board but it is a little more bearable having had some sleep

Dude I got it sorted, well sort of...

I picked the Dell Resource CD to pieces and after opening the Boot.img in WinImage I discovered they were using extcd.sys There is also a ramdrive.sys file on there so I copied that across as well, copied the Autoexec.bat and config.sys files which appear as follows:

Autoexec.bat

@echo off
:: DRMK boot image file autoexec.bat, REK 3/2007

:: The standard exit for this process is to the root of the CD/DVD ROM
:: It will look for a process entry point named \dosmenu.bat and
:: will not complain if such a file does not exist. Ramdrive and
:: Smartdrive are implemented. Most executables are moved to the ramdrive.
:: Comspec and path are redirected to the Ramdrive.

PROMPT $P$G
cls
@echo working...
@echo
@echo

LH smartdrv >nul

:: Get drive letter for Ramdrive
kolache !ramd >nul

:: Define the drive letters, create an optical device
MSCDEX.EXE /D:EXTCD001 /L:f

set cdrom=f:

path=%RAMD%\;%CDROM%\;a:\

:: Load the Ramdrive, reset comspec, temp and path
copy *.com %ramd% >nul
copy *.exe %ramd% >nul
SET comspec=%ramd%\command.com
set temp=%ramd%\
set tmp=%ramd%\

ghost.exe

Config.sys

:: DRMK boot image file config.sys, REK 3/2007

cls
echo
echo
echo Press a key to start from the CD/DVD...
timeout 10
getkey
onerror < 256 goto Next
bootnext

:Next
echo
echo
echo Continuing to boot from CD/DVD...

quiet on

device=himem.sys /testmem: off (I put a space before "off" to axe the smiley)
device=extcd.sys /D:EXTCD001

quiet off

devicehigh=ramdrive.sys /e 32767

lastdrive=z
files=100
buffers=20
dos=high,umb
stacks=9,256

I naturally comes up with a few errors but eventually boots to ghost and I have successfully restored an image.. AWESOME drinks all round.

Next step is to wittle the autoexec.bat and config.sys files down to only include the essentials and that should neaten it all up.

Thank you very much for your prompt response though, it is great to have this type of resource available.

Good detective work--glad you have a functional solution.

You can press *F8* during boot sequence just after the POST--you should get the DOS option to have *step-by-step* confirmation of each command line in your boot files--you can accept or reject each line to determine what is needed vs what you can leave out.

Looks like the *extcd.sys* is the needed replacement for the other possible DOS drivers to mount the optical drive--I suspect you can simply put that in place of *oakcdrom.sys* on other boot disks or discs and it will work.
