OS2LDR

OS2LDR is known as the OS/2 Loader.

OS2LDR module, running in real mode, sets up the PIC chips, sets the PIT timer chips, queries the BIOS for hardware configuration data, reads various CMOS and ROM information, and finally loads (i.e., reads in and applies fixups to) OS2KRNL and transfers control to it at its start address, syiInitializeOS2.
