$oem$ & Booting clarification needed

[Stuntgp2000]

Hi everyone.

I hope you have time to read all I'll write.

I've been trying to avoid unattended installation from hard disks as I could, but now, it seems to me that time has come to face this issue.

First of all, I had no problem with my unattended XP SP2 Corporate CD. It's a bootable CD that I've created myself using nero. I've made many installations using this CD at work by booting & installing from it without any problem.

Yesterday, I went to install a laptop using the same CD after setting up the Bios to boot from CD first. However, when I went to install, I had a strange message from bios "Non-Emulation booting" and the laptop freeze. I tried to boot from Win98 CD & it booted normally.

Then I tried to install XP from DOS. I have noticed that $oem$ looks like this _oem_ & long files are shown without the symbol ~1 at the end.

1) Is this due to non standard ISO format of my CD or it's due to DVD-RAM that equips that laptop ? or just both ?

before moving to the next point, I've searched & found that I have to update the version of the bios in order to boot.

the next issue is that to make an unattended installation from DOS I have to put $oem$ under I386 which mean I've to create two versions of the same CD one with $oem$ parrarelled to I386 & one with $oem$ under I386. But thanks to Alanoll this is no longer a problem.

here's my question, Installing XP from 98 installed requires $oem$ under or pararelle to I386 ? because I've installed 98 on that Laptop then installed XP from it and I had no update nor any stuff I had at $oem$ installed ($oem$ is at the root of the CD)

All I hope is not an answer to may two question but rather to see a sticky topic which explain $oem$ from A-to-Z used with different unattended modes.

Thanks in advance.

I forgot to say that this laptop have no floppy disk drive. and I created my cd with Nero using No-Emulation & to read the first 4 sectors.

I've made a seach on the issue and I've found that this error "Non-Emulation booting" appears on laptops that don't have a floppy disk drive integrated but I don't think this is the only cause & and I've found this

"An unattended install of Windows 2000 can be performed by booting from CD-ROM. Therefore, your computer must support booting from CD-ROM and must adhere to the El-Torito non-emulation specification."

and also

"Anyway, based on this I think it is a problem with the Toshiba drive not recognizing the boot capabilities of this particular disk (I am also booting a slipstreamed Win XP disc). Other discs, including of course the restore CD, work fine. I noticed that the restore CD uses some kind of floppy boot emulation, while the XP cd uses "No emulation booting". Maybe the Toshiba drive does not support this (whatever it is)?... "

Yes, the DVD Ram I've is a Toshiba drive.

I'll report all I find in this issue.
