Simple Boot Flag function
This function automatically optimizes the behavior and boot performance of the BIOS and operating system, based on the installed operating system and previous boot.
If this function is Enabled and once a Plug and Play-capable operating system, such as Windows 98, is installed, the system BIOS does not configure such hardware resources as system interrupts, memory ranges, and I/O port ranges for all the devices in the system.
If you are going to use a non-Plug and Play-capable operating system, disable this function so that the BIOS will configure hardware resources.
(Important Notice)
If you are using multiple operating systems in addition to Windows 95/98, you must DISABLE the Simple Boot Flag in Easy-Setup.
To modify the Simple Boot Flag:
1. Hold down the F1 key on the ThinkPad and power on the system.
2. Open the Config icon.
3. Open the Quick Boot icon.
4. Set Simple Boot Flag to Enable or Disable depending on configuration.
