ROM Images for Various IBM PC Family Devices


The intention of this webpage is simply to provide content, that without modification, is suitable to populate a replacement ROM/EPROM  (e.g. create a replacement ROM/EPROM of version 4.66 to replace a faulty version 4.66 ROM/EPROM).

Out of scope is upgrade information.  If you are seeking a version upgrade, then 'do the research'.  Some upgrades may have special hardware requirements/considerations.  Some upgrades may require different switch settings.

The 'Make' and 'Model' columns show the parent device that the ROM image was created from.  The ROM image may also be suitable for other make-models.  It is not in this webpage's scope to identify all possible uses of a particular ROM image.

Sum:  Checksum (via simple byte addition)
Copy:  How the image was created. D=direct (e.g. from EPROM programmer) C=computer (using computer [e.g. DEBUG software])
Source:  Person at the VCFF (or at phantom.sannata.ru) who supplied the image.  Note that the supplier isn't necessarily the same person who created the image.

Note that an image created by a computer is not always suitable (i.e. without modification) for use in a replacement EPROM.  It depends on the device.  For example, the content of the ROM on an IBM EGA card is ordered differently to how the content is presented to the computer.

Shown at here, are some people/companies that can burn EPROM's for you, using ROM images below.

Note 1 The ROM socket is fed inverted address lines.
That is why the ROM content is reversed (last byte first, first byte last) compared to how the computer sees it.
   
Note 2 First two bytes are 55/AA indicating BIOS expansion ROM.  Third byte is 20 indicating code size in the 32 KB sized ROM is 16 KB.
Therefore we'd expect the 8-bit checksum of the first 16 KB to be 00.
The 8-bit checksum of the first 16 KB (addresses 0000h to 3FFFh) is instead FE.
Not sure what is going on here. Need to look at what is presented to the PC.
   
Note 3 First two bytes are 55/AA indicating BIOS expansion ROM.  Third byte is 1C indicating code size in the 16 KB sized ROM is 14 KB.
That explains why the 8-bit checksum of the entire 16 KB is not 00.
As expected, the 8-bit checksum of the first 14 KB (addresses 0000h to 37FFh) is 00.
It is interesting to note that the actual code size is greater than 14 KB (take a look).
   
Note 4 First two bytes are 55/AA indicating BIOS expansion ROM.  Third byte is 0C indicating code size in the 8 KB sized ROM is 6 KB.
That explains why the 8-bit checksum of the entire 8 KB is not 00.
As expected, the 8-bit checksum of the first 6 KB (addresses 0000h to 17FFh) is 00.
   
Note 5 First two bytes are 55/AA indicating BIOS expansion ROM.  Third byte is 0C indicating code size in the 16 KB sized ROM is 6 KB.
That explains why the 8-bit checksum of the entire 32 KB is not 00.
As expected, the 8-bit checksum of the first 6 KB (addresses 0000h to 17FFh) is 00.
It is interesting to note that the actual code size is greater than 6 KB (take a look).
   
Note 6 First two bytes are 55/AA indicating BIOS expansion ROM.  Third byte is 20 indicating code size in the 32 KB sized ROM is 16 KB.
Therefore we'd expect the 8-bit checksum of the first 16 KB to be 00.
The 8-bit checksum of the first 16 KB (addresses 0000h to 3FFFh) is instead FE.
Not sure what is going on here. Need to look at what is presented to the PC.
   
Note 7 The system board appears to be designed to take either one 4KB ROM in socket A49, or two 2KB ROMs in sockets A49/A50.
There are links for that, and links to accommodate certain different types of ROM.
My 912B has a single 4KB ROM in socket A49, a MM52132, which from a reading perspective, is the same as a 8332 ROM.
By modification, I successfully used a TMS2532 in the A49 socket.  To do that, after burning, I took pin 21 high, which can be done by either of the following:
    1. Alter links W35/W36; or
    2. TMS2532 modification. Photo here.
   
Note 8 According to old adverts, Priam released variations of its 'InnerSpace' disk system (e.g. ID20, ID60-XT, ID130, ...)
This Priam copyrighted ROM is from a particular variation, one where the controller is a Western Digital model WD1002S-WX2.
ROM contents include "InnerSpace ID" and "ROM BIOS Version 1.0" and "Copyright PRIAM Corporation 1985".
   
Note 9 TMC-830:  According to here, the version 7.0 BIOS from the TMC-850M will work.
   
Note 10 TMC-860M and TMC-885M:  According to here, the version 8.2 BIOS from the TMC-850M will work.
   
Note 11 VGA BIOS ROM from a multiunction card of unknown make and model.
   
Note 12 First half is EVEN bytes, second half is ODD bytes.
   
Note 13 Contains two versions of the BIOS: 6.3U and 5.55.

A3: ROM type is 2316E (as printed on the PCB). I successfully used a NEC D2716D EPROM.
A49:  See note 7 above
