I've got a computer running Windows 98. After the POST runs, it locks up. I've gone into the BIOS and set it to boot from the A drive first. When I insert a boot disk into the A drive, the computer will boot to an A prompt. I can type DIR and see the directory contents. However, when I type format c: \s, the computer says bad file name or command. I've tried a variety of different methods and I've had no luck. Any ideas how I can reformat this C drive to reinstall Windows? By the way, I've also tried switching the BIOS to boot from the CD with the Windows 98 CD in the drive. The computer says Booting from ATAPI CD-ROM...Failure. I'm open to suggestions...
