Authors/Port authors:

QSINIT is a replacement of OS2LDR created from scratch.



This software is distributed as compressed package. You have to download and manually install it; if prerequisites are required, you will have to manually install them too.

Manual installation

Program is distributed as ZIP package: download to temporary directory and unpack to destination folder. See below for download link(s).

Latest version works fine with current version of ACPI.PSD once /VW parameter is specified (e.g.: PSD=ACPI.PSD /VW). To install QSINIT:

  • rename original IBM OS2LDR to OS2LDR.OLD;
  • unzip OS2LDR and QSINIT.LDI to the root of boot drive;
  • create OS2LDR.INI in the root (see readme.txt for example) and reboot.

This will solve the "just 512 MB of RAM" problem on EFI.
