Adrians Digital Basement | Fixing and improving the IBM PC/AT 5170 BIOS (bonus shorted tantalum fix) @adriansdigitalbasement | Uploaded July 2021 | Updated October 2024, 4 hours ago.
The IBM PC/AT 5170 has some issues with the stock BIOS that causing boot time errors and also prevent you from using a IDE hard drive/CF card/SD card with the machine. Normally people replace the BIOS with a more modern AMI or Quadtel BIOS.
In this video I talk about how to fix the issues with IBM's BIOS so you can run original IBM code (albeit patched) to maintain some of the machine's original purity.

IBM PC AT 5170 Series:
Part 1: youtu.be/hKgIdBIeCN0
Part 2: youtu.be/QFpJ3uWIqVQ
Part 3: youtu.be/qO3xrl0XR-4
Virtual Box 6.1 running MS-DOS 6.22 and IBM MASM 2.0. Used this to compile the code and generate the BIN (without correct checksum)
virtualbox.org
Managed disk images with WinImage 10.00
winimage.com
Used HxD Hex Editor 2.4 to do binary file editing, and perform the 8-bit checksums correcting the last byte
mh-nexus.de/en/hxd
Used RomWak to split/merge the binary files into odd/even version
github.com/freem/romwak
RomWak was complied on the PC using TCC 0.9.27
bellard.org/tcc
To run a virtual 5170 I used Mame 0.207 (version is important)
