I have an ASUS P5B (non-delux) and I am trying to update the BIOS to be able to use the Wofdale core (1333) but I'm running into a huge problem. I don't have a floppy drive. I have read about others using a bootable CD that brings them into the updater with the updated BIOS file on it. Also I don't have the CD that came with the Mobo as we have moved a couple times since I got it and...well you know how that goes.

Is there anyone who can help me?

As noted, the lack of a floppy and the lost motherboard CD are common hurdles — the cleanest, safest fix is to flash from the board itself rather than using an OS-based updater.

Prepare the USB stick: confirm the exact board model/revision (P5B non‑Deluxe) on the ASUS support page, download the matching BIOS package, extract the archive and copy only the BIOS image to the root of a small USB drive formatted FAT32. Use a rear-panel USB port. At boot press Delete to enter setup, launch the ASUS EZ Flash 2 utility (Tools menu), point it at the USB file and follow the prompts. Do not interrupt power while the flash runs; wait for the utility to report success, then reboot and Load Optimized Defaults before reapplying any custom settings (SATA mode, boot order, overclocks).

Safety notes and alternatives: follow ’s warning — avoid Windows/online flashers; a crash during an OS-based flash commonly bricks a board. If EZ Flash 2 is not available on a particular BIOS, the next option is a DOS-based flasher from bootable media (CD or USB) using the manufacturer’s flasher utility, but that route is more error‑prone and should follow the official instructions precisely. Ensure mains stability (use a UPS if possible) and record the current BIOS version before proceeding.

One final point: verify the P5B CPU support list for the exact Wolfdale 1333 model intended to be used — Wolfdale support was added in later BIOS revisions for some boards, so match CPU model to BIOS version before flashing. This advice expands on ’s pointer to ASUS tools while echoing ’s caution about online updaters.

from this Asus website !

EZ Flash 2
Simply update BIOS from a USB flash disk before entering the OS
EZ Flash 2 is a user-friendly BIOS update utility. Simply launch this tool and update BIOS from a USB flash disk before entering the OS. You can update your BIOS only in a few clicks without preparing an additional floppy diskette or using an OS-based flash utility.

yes, the USB is the way to do it.

I think ASUS have an online BIOS updater. Whatever you do DON'T USE THIS :)
