Reset Configuration Data 

If you install a new piece of hardware or modify your computer s hardware configuration, the 

BIOS will automatically detect the changes and reconfigure the ESCD (Extended System 

Configuration Data). Therefore, there is usually no need to manually force the BIOS to 

reconfigure the ESCD. 

However, sometimes, the BIOS may not be able to detect the hardware changes. A serious 

resource conflict may occur and the operating system may not even boot as a result. This is 

where the Reset Configuration Data BIOS feature comes in. 

This BIOS feature allows you to manually force the BIOS to clear the previously saved ESCD 

data and reconfigure the settings. All you need to do is enable this BIOS feature and then 

reboot your computer. The new ESCD should resolve the conflict and allow the operating 

system to load normally. 

Please note that the BIOS will automatically reset it to the default setting of No after 

reconfiguring the new ESCD. So, there is no need for you to manually disable this feature after 

rebooting. 

Yes / No 

Large Disk Access Mode 

This option determines whether a hard drive with more than 1024 cylinders, more than 16 

heads and or more than 64 tracks per sector is present on the system. Set this option to DOS 

if such a hard drive is present. Else, set this option to Other.  

Virtually, all modern hard disks have these characters so leave this option at DOS, unless you 

know otherwise. 

DOS / Other 

Route Port 80h cycles to 

This feature allows you to route Port 80h I/O cycles to LPC or PCI bus. 

LPC / PCI 

Legacy USB Support 

When enabled, the BIOS takes control of the USB ports. Enable this only if you run an OS that 

does not support USB (e.g. DOS) or when you have USB hardware like USB mice that you 

want to use even before the operating system loads.
