Dell c600

I'm a volunteer firefighter (and certified computer tech), my training coordinator handed me this ancient machine and asked if I could get it working.  I assumed some mundane issue, however it turns out the machine had a BIOS password and hard drive password.  He purchased the machine at Goodwill for a child's use.  I  unable to wipe the hard drive as I lack an ide to USB converter.

I was able to bypass the BIOS password however, without the hdd password or setup configuration password I  unable to even boot from a CD.  I have searched high and low for a workaround, but hdd passwords are "impossible" to crack unless you use an ide sniffer.

As I am unable to provide any real ownership information is there a back door password for the setup configuration within the BIOS so I can at least boot from an alternate media?  I know this laptop is ancient, but he is the type that he spent money on it, he wants it working lol.  Any help would be appreciated.
