use bios from Toshiba Satellite 3000 on a Satellite 2800-202?

I'm considering this option because the Satellite 2800 is limited to 192 mb ram (64 mb soldered on + 128 mb SD100 ram).
I bought a 256 mb chip but the bios does not accept it.

The machines are not all that different, the 300 has a cpu that is about 250mhz faster and a nvidia Geforce video instead of the Savage chip on the 2800.
Some of the later 2800s did support 128+256 mb but the bios files come packaged together, does not seem possible to choose the 'wrong' one. I could try to look at all the installers i can find of course.

So, is this likely to brick my old Toshiba? I guess it will if this is truly a hardware limitation.

I wouldn't risk it man.... Even though the systems are similar, the overall underlying circuits are most likely different, thus using a different BIOS could and will most likely brick your computer.

Thanks, better not risk it then. The pc is still useful when i work in a big reading hall,
no one bothers to steal it..
Runs quite well with antiX, openbox with no icons, no login manager, a browser, dict (Lexica) and a dictionary running in wine. And Abiword etc too. Have to avoid running too much at a time.
Will try to increase size of swap partition.
The RAM chip cost only $10.
There is a bios for a 2805 though, made for XP. Less of a risk
Don't wanna lose the old workhorse

It is sometimes possible to 'crossflash' BIOSes (eg, if you have a nForce 2 chipset motherboard from gigabyte, it is _someimes_ possible to flash using a asus nforce 2 BIOS) but that is still risky, even with desktop boards. In situations where it does work, you can sometimes have devices disabled (eg, if the sound/netowrking chips differ from board to board)

With the added complexity of laptops, even a well researched crossflashing could still brick it.

now, as long as the machine starts it will be possible to flash back the old bios. Most bioses start whatever the video card I guess but this is some kind of special toshiba bios so..
