If it's a DOS based virus it might be an MBR type that could possibly alter values in your CMOS. I'd shutdown the PC completely and then reboot, get into the CMOS and check the settings. Then use a write protected boot floppy with the fdisk utility on it and do fdisk /mbr. Whatever you do, be sure to not just do a warm boot back into DOS otherwise the virus will still be in memory and just put itself back in the hard drives MBR.
