Typing in all capital letters in a post on the web is considered to be the same as if you shouting, and very rude !
This is an old computer model.
I'm guessing you probably want to be able to use hard drives larger than 137 gb hard drive manufacturer's size and have them seen as their full size rather than max 128 gb in the bios and in Windows.
I took a look at your Maintenance manual for your model.
Inside of it it's dated 2001.
The manual is usually the same age as when the model was first released, or up to a year or so newer.
It's probably impossible for your motherboard's main chipset to be able support recognizing any hard drive larger than 137 gb hard drive manufacturer's size as it's full size, no matter which bios update you use.
I searched the web with: "hard drive" "Netvista 8303"
and found absolutely NO hard drive upgrades larger than 137 gb in listed "hits".
If there WERE bios updates than supported hard drives larger than 137 gb you would find those listed on the web.
The model originally supported up to 120 gb hard drives.
If you wanted to have the the computer recognize a hard drive larger than 137 gb hard drive manufacturer's size as it's full size, buy yourself a PCI EIDE (a.k.a. PATA) hard drive controller card, or a PCI SATA hard drive controller card if you want to use a SATA hard drive, and use that in a PCI slot, connect the hard drive to that card.
Apparently your mboard has 3 PCI slots, an optional AGP slot, 2 DIMM slots, two IDE data headers, a floppy drive data header, and it came with a floppy drive.
Don't install it in the PCI slot closes to the center of the mboard - that slot usually shares it's IRQ with the video and if so only PCI video cards are likely to not have problems when installed in that slot.
NOTE: In order to be able to boot an operating system from a hard drive connected to the PCI drive controller card, you must be able to select SCSI in your bios Setup Boot Order or similar settings, and have that SCSI in the list before hard drive or similar. Floppy drive should be listed first, then CD-Rom or similar, then SCSI., then hard drive.
If there is no SCSI to select, the larger than 137 gb drive, or any hard drive connected to the card, can only be used for data. You also won't be able to boot the computer from a bootable CD or DVD in an optical drive connected to the card.
If you use a SATA hard drive controller card and want Windows to be able boot from a partition on a SATA drive connected to it, when you run XP's Setup, you must
- press F6 when you see that line at the beginning of loading files from the XP CD and provide the drivers for the card's SATA controller on a floppy disk in the floppy drive
- or - make yourself a "slipstreamed" XP CD that has the SATA controller drivers integrated into it - if you do that you might as well integrate the SP3 Windows updates into the CD at the same time - e.g. you can do both with the freeware nLite program - and use that "slipstreamed" CD along with the original Product Key to install Windows XP on the SATA hard drive.
The XP CD you use must have SP1 or later Windows updates integrated into it in order for it to have the built in support to recognize a hard drive larger than 137 gb hard drive manufacturer's size as it's full size (the bios and Windows sees the drive as it's binary size - 137 gb hard drive manufacturer's size = 128 gb binary size).
If your XP CD doesn't have SP1 or later updates integrated into it, follow directions found on the web to make yourself a "slipstreamed" CD with the SP3 updates integrated into it.
