In some cases, your system may display a message indicating that Linux BIOS programming is in progress. There can be several reasons for this problem.

This means that you simply rebuild the IBM PC, PC XT, PC AT, and PC XT 286 BIOS source code by scanning and decoding it against the BIOS listings found in the IBM technical reference manuals. This historically significant location code is shown here for conservation purposes.
IBM PC version 1 04/21/81IBM PC version 2 10/19/81IBM PC version 3 10/27/82IBM PC XT Adaptation 1 11.08.82 (also used on any portable PC)IBM PC XT releases a couple 01/10/86IBM PC XT Version 3 09/05/86IBM PC AT Version 1 01/10/84IBM PCAT version 2 10.06.85IBM PC AT Version 3 11/15/85 (used on PC AT 319 339 models)IBM PC XT 286 04/21/86
• All 3 IBM PC BIOS variants and their first IBM PC XT BIOS were created using Intel ASM86 on an Intel development system. In each example, the BIOS source code is one large file, and the BIOS code is typically 8 KB in size and located at F000:E000
.
• IBM PC AT BIOS version 1 is integrated into IBM MASM 1.0 under DOS. This is the first IBM BIOS to use a set of source files. Because IBM MASM 1.0 does not support 80286, there is also a macro file (IAPX286.MAC) previously associated with generating the necessary opcodes. This is by far the first BIOS divided into two parts: the main programThe BIOS firmware is located at F000:0000 and the compatibility field (ORGS.ASM) is located at F000:E000. An additional FILL.ASM image has been added to define the entire area between the end of the BIOS keycode and the backwards compatibility section, allowing the BIOS to fully link. It is currently unknown how this was originally processed.
• The IBM PC AT Model 2 and 3 BIOS and the IBM PC XT 286 BIOS were designed to allow the use of IBM MASM 2.0 under DOS. They certainly look like the PC-AT version in at least one BIOS, but there are fewer original MP3s because some of the files have been merged and practically all the cleaning has been done. IAPX286.INC is undoubtedly used to generate 80286 protected mode opcodes that were not provided by IBM 2 masm.0. FILL.ASM serves the same purpose as this tool for the PC-AT version of a single BIOS, although in each case the computer file is specific to the specific BIOS being created.
• Some versions of the IBM PC XT and BIOS 3 were created using IBM MASM 2.0 under DOS. The latest PC XT BIOS code has been restructured to look like a replacement for the PC AT BIOS, so there are several source files. Same as BIOS AT-PC, the code is unmistakably divided into two parts, although the pram section is in the POST.ASM file. In addition, the FILL.ASM file is used to define the area between the end of the main BIOS code and the capabilities section.
• The code below is present for all versions of the PC-AT BIOS, and the PC-XT-286 BIOS generally does not appear in published home directories. It is derived from public images in ORGS.ASM and code disassembly. We don’t know what this code is for.
