Is it true that Iomega CDRW23040INT-B can be Upgraded to Lite-On 48125W?

ANd instantly becomes at 48X time R ? and 48X W ?

Is this the correct BIOS ?

And can the process be reverse ?

look here;

I was pretty sure that one(it’s the 32X, right?) was a LTR-32123S and then not upgradable…

But I may be wrong.
