Nop, all ways of disconnecting the internal drive have already been
tried. Still believe the best way is modifying files to bypass the
master CD-ROM check.

Bill, couldn't understand on booting from the hard drive and how can it
help in the recover CD not going for the internal drive. Help please

Guerreiro, it is not very easy to follow through your startup files
and understand what and where you should modify.

Are you saying the machine does boot from the recovery CD?
Then what, can it not read the CD at all after boot?
What type of screen or prompt do you get after boot?
Is there a menu or just a simple Dos-prompt, like A:\
If you are at a Dos-prompt, what happens if you type D:
and make [Enter]?
If it responds with a D:\ -prompt then what happens if you type dir
and make [Enter]?

Do you have, or can you make a bootable USB-stick?

The machine boots with the recovery CD in the non internal drive. It
installs the basic DOS controllers including all optical drives and a
third party partion for the recovery. Then automatically goes for the
last autoexec command: lh %CDDRIVE%\recovery.exe where it initiates the
recovery process. For all the process it never gives a DOS prompt. Right
away it stuck in a DOS based appearance with red screen and yellow
letters asking to put in CD1(system CD) in master CD-ROM. It
acknowledges that the CD isn�t in the correct drive although all is
working.

Yupii made it!

At first I thought it was because the line a:\ckrom.exe in autoexec.bat
and the program it runs that checks the drive in use, so I erased it.
Then I realised that although the recovery cd boots from the USB drive
it doesn't install USB/CD drivers and it never recognizes the drive.

Problem solved using USB_CD.SYS instead of OAKCDROM.SYS and changing it
in the config.sys. It installs the USB CD drive instead of the internal.
Still I keeped a:\ckrom.exe erased plus physically disconnected the
internal drive.

Also came to find post in another forum with the same problem 8 years
ago:

Many thanks

There's a program called the PLOP boot manager
http://www.plop.at/en/bootmanager.html

I've used it to start from a floppy, then boot from
a device selected in plop.
