My motherboard is I845PE, RAM 256MB, CPU is P41.8A GHz, the hard disk is 60GB, recently i bought a 160GB hard drive to store video files, but when i installed, boot and found motherboard does not recognize the hard drive, What is the problem, how to solve this?
A: Despite the current 160GB hard drive is mainstream, but in some non-mainstream motherboard, we found 137GB capacity cannot support the restriction, for which you can update motherboard BIOS to solve the problem, if the companies did not provide updated BIOS program, BIOS Patcher can try to use the tools to patch the motherboard BIOS, of course, even if a pair of 137GB hard drive to solve the BIOS constraints, but common operating systems do not support 48-bit addressing in default, the same can not support more than 137GB hard drive, which we can use the Windows 2000/XP CD boot to build a capacity of less than 137GB primary partition (you can also use the Windows Me Startup floppy disk partition in Fdisk primary partition) during the installation process. Extended partition use Disk Management tool to partition and formatting after installed the Windows 2000/XP.
But Windows 2000/XP itself does not support 48-bit addressing, even if the capacity of all the partitions are less than 137GB, there will be room for identification error. To do this, Windows 2000 Service Pack4 patch must be installed, and Windows XP Service Pack2 patch must be installed. After the patch is not enough, you must modify the registry that can really activated 48-bit addressing. For Windows 2000 systems, expand the registry HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ ACPI \ Parameters, and then create a new key item called EnableBigLba of DWROD, its value is set to 1; for Windows XP system, expand the registry HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ ACPI \ Parameters, and then create a new key item called EnableBigLba of DWROD, and its value can be set to 1.
