It is intended for booting OS/2 using these bootloaders. OS/2 booter loads all needed files to memory (they are specified as multiboot modules) and then installs special micro- and minifsd which read files from memory by requests of os2ldr and os2krnl. So, you can think of it as an mbi (multiboot info) micro- and minifsd which boot text/html 2019-01-13T20:15:50+00:00 Anonymous (anonymous@undisclosed.example.com) http://osfree.su/doku/doku.php?id=en:docs:boot:freeldr:history&rev=1547410550&do=diff Project history In 1999, David Zimmerli wrote an article in EDM/2 in which he inaugurated the project aiming to replace OS2LDR, OS/2 operation system loader. He wrote a stub program which was loaded by the boot partition MicroFSD and tested the use of its routines.

It was inspired by some DOS program, which modifies config.sys in memory. Os2csm installs itself in place of os2ldr, and renames os2ldr to os2ldr.bin. Os2csm hooks onto int 13h interrupt handler and analyzes the information read through int 13 routine. The config.sys file contains directives, analogous to C preprocessor directives, and each 512 bytes of config.sys file (each disk sector of config.sys) has a special comment with a spec… text/html 2014-05-21T21:33:01+00:00 Anonymous (anonymous@undisclosed.example.com) http://osfree.su/doku/doku.php?id=en:docs:boot:freeldr:relnotes&rev=1400707981&do=diff FreeLdr 0.0.2 release notes. 1. An introduction about a concept of a multiboot loader. The osFree project boot team presents the first preview of its bootloader -- FreeLdr. The FreeLdr is a general purpose bootloader for different kinds of operating systems, using the multiboot protocol, the common protocol for interacting between kernel and a bootloader. This protocol defines the format of kernel image (a so-called multiboot header in first 8192 bytes of kernel image) and a format of informat…
