Looking for Version 3.01 Boot ROM for 9000 425/433


 

I’ve upgraded my HP 9000 400s to a 433s by replacing the 68030 processor with a 68040.

This means I also had to change the boot rom, the 1818-5108 rom on the motherboard wasn’t compatible with 68040.

Long time ago I copied an image and a how to description from the internet, but that image doesn’t work also it has the same checksum as the 1818-5108.

Next I tried the boot rom image from bitsavers (1818-4990) , that worked. But this is a Version 2.0 rom image.

So now I’m looking for a Version 3.0 or 3.01 image for the 9000 425/433s.

If anyone has a copy please let me know.

Rik,
I'll take a look at my 425t spare boards if I can pull the ROM.

Rik,
I think I got what you need, but no possibility to copy the ROM. Let's discuss via PM.

What is the Intel number on the 40 pin chip?

Thanks
Glenn

Glenn,

The 27C2048 is not a HP part-number, it is an generic component made by AMD and also made by other manufactures.
And the 1818-**** numbers I mentioned are for the programmed boot roms.
