Hello Sun Managers,
Well, first of all I want to thank to:
Michael Cunningham
John Sullivan
Imre Kolos
Timothy Lindgren
The most fully explained was Imre Kolos:

Thats right, actually the bug's description is:
-------------------------------------------------------------
Bug ID Synopsis
4155713 Can not use IDE Disks greater than 8GB to full
capacity
Category kernel
Subcategory driver
State integrated
Description
We can not use IDE disks greater than 8GB to full capacity
on darwin.
The way the capacity is computed in the ide target disk
driver is - it uses the CHS values given by the drives identify command to
compute the capacity.
In drives greater that 8GB, the ide drive manufacturers
show the the CHS value of - 16383C, 16H, 63Sectors/track which does not
cover the complete disk.
This is due to BIOS legacy on IBM PC's. Most of the BIOS
can not understand cylinder > 14 bits.
The complete disk can be accessed through the LBA value
which is to be used to access beyong 8GB (approx).
Need to modify "dad" target driver so that it uses the LBA
value to compute the capacity rather than relying on CHS value.
-------------------------------------------------------------
And as John Sullivan said, it seems they solved it in Solaris 7 but not
yet in Solaris 2.6:
>Unfortunately, Sun never fixed the EIDE driver in 2.6. Solaris 7
>supports disks >8.4G, Solaris 2.6 only sees the first 8.4G or so.

I did my own tests and installed Solaris 7 hw 3/99 on an ultra 10 and
saw the 13GB also could install the solaris 7 on it.
Unfortunatelly the system won't boot (some problems with the /var slide).
There is another problem already talked on the sunman-list about a kernel
patch 106541-05 that doesn't properly process postpatch.
It seems that I have to run the upgrade option.
My original question:

Thank you all!
P.S. I apologize for the the late summay and for some problems with our
DNS that made the original message repeat several times on the list.
