Can I upgrade BIOS of Inspiron 1300 with out-of-order Battary? DVD/CD-Device issue.

[Dakare]

Hi everyone!
I need to upgrade BIOS. The Dell Inspiron 1300's BIOS upgrade software needs a working Battary inserted. I have no one. Is there a trick to manage?
And else. I've replaced HDD with SSD. Found IDE SDD After that, my Laptop begins to warn me: "There's a device unknown or wrong inserted. Press Esc to continue". I press Esc and OS begins being booted OK. After any first time OS booted the DVD/CD-Device isn't founded by OS DeviceManager. I command to reboot OS. After the second - OK! The DVD/CD-Device is founded, working great! How to manage? Pleace, help!
