Looking at the datasheets they are both 2Mbit parts and both are 5V
program. So they should be equivilent.
i have tried writing the RD1 with a image file, but it always fails
:( anyone any pointers?

What's up here? Has the factory bios set some lock so you can't
enable bit 4? What does that bit do?

You IDed both parts correctly which means that writes to flash seem to
be happening. Can you read the parts ok?
If so then you might try flashing in your LinuxBIOS image and then
read the image back from the part to see if it wrote anything close to
what you expected where you expected.
