I am running and older compaq presario (4712). When I try to boot up, it asks how I want to boot (normal, safe, command, etc.), but once a choice is made, it proceeds to tell me that there are corruptions in the config.sys setup and it will not boot up. As far as I am concerned, I could care less to keep the original setup, but it will not boot to the A drive or the CD-ROM either and I cannot seem to get to the bios to make the A drive the primary boot device. Any ideas out there that might help me either get the system back the way it was or to boot the thing up to the command prompt in order to start over again?
