Windows 98 Boot Process
- POST - Hardware tests
- Plug and Play Configuration -Windows 9x is a Plug and
Play(PnP) operating system. In order for PnP to work, the BIOS, hardware and operating
system must all be PnP compliant.
- Master Boot Record - The MBR is located.
- IO.SYS - This file loads drivers and executes CONFIG.SYS,
MSDOS.SYS and COMMAND.COM
- COMMAND.COM - Loads AUTOEXEC.BAT
- Windows core files are loaded
- WIN.COM - This file begins the loading of Windows 9x system
- KERNEL32.DLL/KERNEL386.EXE - These files contain the core
operating system and is responsible for loading device drivers.
- GDI.EXE/GDI32.EXE - These files are responsible for loading
the basic GUI or graphical user interface.
- WIN.INI - Along with WINFILE.INI and SYSTEM.INI, these files
provide backward compatibility with older 16-bit applications and are not required in
order for 32-bit applications to run under Windows 9x. Most of the functions of these
files are now stored in the registry files.
7.The startup folder is checked for
applications to load on startup.
Windows 9x also replaces many of the DOS start-up files
such as IO.SYS, MSDOS.SYS and COMMAND.COM with newer versions. Most of the functions of
the CONFIG.SYS and AUTOEXEC.BAT files are now handled by the new IO.SYS file, although
entries in CONFIG.SYS will take precedence over entries in the IO.SYS file.
