Do you have the full XP CD or is it an upgrade? Have you slipstreamed Service Pack Two (SP2) together with your XP CD and made a new XP CD using AutoStreamer 1·0 so as to get a clean install? Do you have a full '98 CD?
Best to just boot to the new XPSP2 CD (easier to use oldbios.exe on a floppy instead of changing over your BIOS, but you can do either)
When you get to the install use the XP CD to delete all of your partitions and start over. Make an 8·0Gb drive C: (Type 8192) for the XP Operating System and a drive D: using the rest of the drive. (You can have one Primary and up to three Logical drives on one physical drive.)
Formatting is up to you, but I advise formatting directly to NTFS and NOT pre-formatting the drive with FAT32.
That way you get 4096 byte allocation clusters which are optimised for using XP on NTFS and an unfragmented Master File Table (MFT) and your system WILL run better.)
When all is formatted just proceed with the installation.
When complete run chkdsk and defrag, then add your Anti-Virus and Firewall (I use AVG & Zone Alarm), re-connect your modem, go-online, immediately update your AV and run an AV scan.
Now go to Windows Update site and add all relevant updates for your system.
Add ALL of your other programs, then add SpyBot SD, AdAware SE & SpywareBlaster, update them all and scan thoroughly.
You should install the Recovery Console to the HDD as well to save you time in the future.
With the XP CD in the CD-ROM and whilst connected to the internet type:
(CD-ROM Drive Letter):\i386\winnt32.exe /cmdcons , and press Enter.
Windows will contact MS and download the latest files for the Recovery Console and install them to your HDD. Next time you boot you'll see a 30 second count-down before XP starts.
Reduce this to 4 seconds in System, Advanced, Start-Up and Recovery, Settings. Leave the other setting at 30 seconds.
Make all of your personal settings and when all is to your liking image the drive to CDRs so that you can re-install easily.
Good luck!
