No. You do not start a window-less / command-prompt only version of
WindowsXP with that CD-ROM disc. Instead, you can land yourself at the
Recovery Console command prompt with that disc.
In other words, you should be able to use the WinXP upgrd CD-ROM disc to
boot to the Recovery Console [ read up on using the Recovery Console and
what it can and cannot do ]. This is not *really* booting to Windows XP,
rather a limited Recovery Console that enables some repair operations,
setting the start or not-start of services etc. You can also use it to
partition and format harddrive partitions both in FAT32 and NTFS.
Note though, a bootdisk created with Windows98 can boot your computer,
operate the CD-ROM drive, the A: drive and view all FAT32 formatted
harddrive partitions. The fdisk utility lets you partition and the format
utility enables you to format in FAT and FAT32. It will not be able to read
NTFS formatted partitions on its own. There are third party uitilites that
enable the read and writing NTFS partitions from DOS. And, again, it is not
booting into a window-less/command-promt version of Windows XP - rather, it
is booting into MS-DOS.
