Emergency Repair Disk

Ref article written by Brien Posey,MSCE
I was unable to generate a ERD as Brien outlined in his well written article because my Sharp computer does not have a built in CD-ROM. I was using a Sony External CD-ROM with a PCMICA type II card.
The notebook computer does not have a Config. Sys or Autoexec.bat file so I have not been able to add a device driver. I download the driver from Sony’s web site. I put it on a 1.44mb Diskette. We want to remove the Windows 2000 OS and restore it back to the orginal Windows 98se.Currently all we have is a Windows 98se Startup Disk but it does not reconize the external Sony External CD-ROM.
Please Help
