Windows 98 does not recognize cdrw/dvd combo drive

I have an Inspiron 2650 with a cdrw/dvd  combo drive.  Because of a virus, I had to wipe it clean and reinstalled windows 98.  Originally the laptop had XP but I do not have the original CDs with the machine. 

It is not recognizing the cdrw/dvd  combo as a drive under the Windows Explorer. In the Device Manager under System, for a CD-ROM controller it shows MKEPanasonic CD-ROM Drive.  And it has a ! yellow message. 

I searched the Dell Support site and found the following list of potential drivers for 98:
   HLDS 8X DVD Slim-line DRN-8080B
   HLDS GDR-8081N 8X Slim DVD
   Panasonic UJDA360 Slim 24X CDRW
   Roxio Easy CD Creator 5.2
   Samsung SN 308B 8X Slim Combo
   Toshiba SD-C2502 8X Slim DVD
   Toshiba SD-C2612 8X Slim DVD
   Toshiba SD-R2102 8X Slim Combo

Downloaded all and tried to install all (except the Roxio stuff), but none of them worked.  While doing this madness, I concluded that the drive must be a Panasonic Matshita ujda740 drive, but I’m not sure.  Then I downloaded the Panasonic UJDA740 24X DVD/CDRW firmware version 1.03 and tried to install that but did not work.

Questions:
1.  Is the drive in this machine the Panasonic Matshita ujda740 ?
2.  If yes, where can I find a driver for windows 98?
3. If not, what is the drive I have?

My ultimate goal is to install XP but I can’t do that since I can’t access the CD-ROM.

Thanks.
