Did you load the motherboard drivers for this machine. XP does not have all the software needed to run all of your hardware.
Can some one help me providing a solution, very much appriciated. CD-RW and CD Rom drives not appearing under 2nd IDE Controller
I installed WindowsXP operating system on my Desk top (Compaq 5000 series), CD-RW and CD Rom drives were working correct. After that I did not change any configuration, did not install any software for no reason, both drives got disappeared from my system.
A read some resolution on the internet and deleted "Upperfilter" and "Lowerfilter" from REGISTRY, also ran a VB Script file. Nothing worked.
