Neverending BIOS Loop

Hello,

I would like to please request some help with the following issue, it may be of use to someone else.

I have just restored my toshiba satellite to windows xp. After installing all the proper drivers, I beleive I have updated to the wrong BIOS (ACPI flash BIOS v1.20 for Tecra A4/satellite m45-s359) and I cant do anything to the laptop at this point in time.

I get to the yukon PXE v3.03 (pre-boot execution Environment) and i get into a neverending loop.

PXE-E61: Media test failure, check cable (It always did this prior to malfunction)
PXE-M0F: Exiting PXE ROM
press any key when ready.......

When I press any key it repeats this process.

When the computer powers on The only configuration screen I am able to enter is the BIOS setup by pressing F2, and then F1. the boot order is set to HDD>CD>FDD>LAN. I am not able to get to any other configuration screen by holding '0' when power on or by repeatedly pressing F8. I am able to hold down F12 and manually select my boot device (toshiba has icons at the startup splash screen) but i get the same output. I am not able to boot from my windows cd, Ubuntu 11.04 boot disk, ubuntu 10, or a windows formated boot CD (with the boot.ini file on it). I had even removed the Hard drive to see if I could force the CD boot and i get the same output. I would like to hope that I have bricked the system with the wrong BIOS
ACPI BIOS version 1.20

Here are my current Specs

Toshiba Satellite M45-s2693
Intel Celeron
Windows XP SP3
1GB RAM
Model Number PSM42U-01Q006
unknown Motherboard.
Not Sure what the BIOS was before I flashed it

Thanks in advance for taking the time out to help me with this issue.
