How to insert NCR SCSI BIOS v3.07 or 4.03 into your MRBIOS ?

Recommended by Wim's BIOS...

It's actually simple but varies for each version of mr bios. You need to download a program from Windows95.com called 'Hex Workshop' which allows you to edit files in Hexadecimal. 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 mr bios site describes 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!
