You must call Dell Support.  Once you prove ownership, they will generate and issue the password to you.

No, there is not.  The master password is system-specific.

The cost of a call is about $60 if you're out of warranty, so it's not that expensive.  You must, however, be the registered owner and capable of proving that.

You can reset the BIOS password by removing the CMOS battery located on the system board. This can be a chore, depending on the laptop.

Check the web for sites that publish known "back-door" passwords for various BIOS versions

XPS M1530, Win 10 CU Pro 32-bit
Inspiron E1705, Win 10 CU Pro 32-bit
Dimension 9100, Win 10 AU Pro 32 bit
Inspiron 660, Win 10 CU 64 bit
Inspiron 3668, Win 10 CU 64 bit

Don't waste your time messing with the CMOS battery. The password is not held in CMOS, it is in eeprom. Removing the battery will do nothing except reset the CMOS. The system will still want the password. Removing the CMOS battery does not work on any recent laptop of most if not all mainstream manfacturers. It is an anti-theft mechanism, if it was that easy there would be no point.
