Maybe this belief pervades the whole of the Gigabyte
organization? Maybe, just maybe, they are correct.

We already established that they weren't. It's not the chipset.


But I am left wondering what the hell they are talking about
and why they say there is a 75 GB limit. Any ideas what they
could be referring to (bearing in mind that a BIOS flash is
said to fix it)?

Read my response to Roger.


I must confess I don't really understand the details of what you
have written to him. To take a guess maybe "P-CHS" means "physical
CHS" and you are referring to an emulation of the physcial CHS.


L-CHS is the CHS as used by the software interface (int13 etc.)
P-CHS is a translated CHS as used by the harddrive interface.

For some odd reason software makers and hardware makers went a dif-
ferent route expanding the old 20-bit (528MB) CHS (1024 16 63) to 24-
bit (8GB) CHS. L-CHS expanded the *Heads* register with 4 bits (1024 256
63) and P-CHS expanded the *Cylinder* register with 6 bits (65536 16 63).
Although 2 bits more P-CHS is still limited to C*H*S= 8GB.


Anyway, it seems it may lie deep in the BIOS so I will just accept
that the BIOS flash fixes it. I can't try the BIOS flash for a
while so I will have to wait to see if it really does do the trick.


Btw: doing what trick?
You "have not come across a 75 GB limit" so what do you think you'll notice?



Surely it could not be that they are unable to write "137 GB"
or "128 GB" and instead they wrote 75 GB by mistake?

I hope that flashing this mobo's BIOS will allow it to see the
space about 75 GB on the drive.

After I flashed it I still can't see all of a 160 GB drive.

Maybe it has a 128/137 GB limit now.


You have an ancient mainboard. Why do you expect more than 135GB?

Maybe you should follow all the other threads about LBA-48 and BIOS support.

You are right. The mobo is far too old. I think it may destined
for the trash sometime soon.

Although it has no cash value, I had originally wanted to use the
mobo in a machine to get on the net when my main machine was down.


Why not just invest in a cheap ATA100/133 PCI card then? A second-hand
one in particular would sell for next to nothing. Both promise and
highpoint have issued BIOS updates which add 48bit LBA support for their
range of products AFAIK.

Are there any new mobos around nowadays for Intel's "Slot One" cpu?


New in condition maybe, from leftover stock, but I doubt they've been
produced in years. AFAIK intel's latest were i820/i840 boards and on the
VIA side it was boards with the Apollo Pro 133A, and this was like 3,5
years ago.
