Interesting question Space. We\'ll have to look into it.
BTW I have a Plextor 12/10/32 so I\'ll have to look into whether it will do the 99min. burn. I think I read you could damage your burner if it can\'t do this and you try to make it do it!
Here\'s the summary/method I\'m using to make the WinXP/2k Bootable CD. It has the detail in it that I needed, maybe it will help someone else. It\'s just a little reworking of Oz\'s and the other website\'s 3in1 summary (the_Flames if I remember correctly?).I want to give credit where credit is do so thanks to Oz, Flames, you and everyone else here who helped.
Note -- you will have to have read this thread totally to understand everything in here, but most of us have.
Making a WinXP/2k Boot CD
NOTE - This procedure assumes d: is the drive in use
1. Make the following folders on d:
d:CDroot2kPro
d:CDrootBF2k
2. Copy Full Win2k CD to \'d:CDroot2kPro\' folder
3. Extract d:CDroot2kProBootdisk*.img (Win2k Boot Floppies) to \'d:CDrootBF2k\' folder (with pathname,use WinImage).
4. Copy Full WinXP CD to \'d:CDroot\' folder.
5. Hex Edit \'d:CDrootBF2ksetupldr.bin\' to change all ASCII instances of \'i386\' to \'BF2k\'.
6. Edit \'d:CDrootBF2ktxtsetup.sif\' to change \'SetupSourcePath\' to point to \'2kPro\'.
7. Apply service patch 2 to the \'2kPro\' folder --
w2ksp2.exe -x (extract to a drive other than d:, ie. c: then run the updater)
c:I386UpdateUpdate.exe -s:d:CDroot2kPro
8. Edit \'d:CDroot2kProI386setupp.ini\', and change line \'PID=?

??000\' to \'PID=?

??270\' to avoid entering CD serial no.
9. Copy from \'d:CDroot2kPro\' folder the following files to the \'d:CDroot\' folder --
CDROM_IP.5
CDROM_NT.5
Read1st.txt
Readme.doc
spnotes.htm
*.tst (all .tst files)
10. Copy Bart\'s files to \'d:CDroot\' folder --
loader.bin
diskem1x.bin
diskemu.cmd (Edit to suit OS to install, see Bart\'s instructions)
w2ksect.dat (Win2k bootsector)
wxpsect.dat (WinXP bootsector,same as Win2k bootsector)(Rename while copying \'w2ksect.dat\' to \'wxpsect.dat\')
11.Hex Edit in \'d:CDrootw2ksect.dat\' this ASCII text - \'SETUPLDR.BINBOOTFIX.BINI386\' and change the \'I386\' in this string to \'BF2k\'. Leave \'d:CDrootwxpsect.dat\' alone. It will point to \'I386\' which will be in the \'d:CDroot\' folder now (Copied from WinXP CD in step 4).
12. Right click the above 5 files to change their properties to \'hidden\'.
13. Run CDImage with this command line, assuming \'CDroot\' folder has been made on d: and output file is going to e:
CDImage -lWinXP_2k_Boot -h -o -m -n -bd:CDrootloader.bin d:CDroot e:WinXP_2k.iso
14. Burn iso to CD (approx. 900MB)
