You need to download a hexadecimal editor (for example from www.hexworkshop.com).

The process involves cutting out the blank space at the beginning of the MR BIOS flash image and appending either the NCR flash image v3.07 or 4.03 and saving the file.

Notice the now defunct MR BIOS site described the initial flash image as being 92k but when you download it its actually larger due to this extra blank space.

Cut out the appropriate blank space so the image is 92k, save. Then append the NCR v3.07 flash image by cutting and pasting and save. The file length should now be 108k (92k + 16k NCR v3.07 image). It is OK to append the larger 32k NCR v4.03 image if you like. The total file length will be 124k. This change of offset of the core bios will not hurt anything. As I am sure you know be VERY CAREFUL!
