PH, Doug,

How close to the 7800 or 7900 you think this is?

rest of posting is attached.


side note: google interface sucks big time, back to T-bird for me..

Hard to say.

The DC7800 was Q35/ICH9-D0.

The DC7900 was Q45/ICH10-D0.

Logically, a DC7700 might be ICH8 or ICH7, which would mean the GMCH might
be G31.

If so, then the machine could, indeed, be hacked.

According to HP, the system uses a Q65 Express chipset so it is supported. Same basic hacking should apply AFAIK.

The Q65 Cougar Point chip sets were:

SLH99(B2)

and

SLJ4E(B3)

The B2 stepping is the one with defective SATA II ports, and has been
recalled.

If you pop the cooler off of the GMCH and see SLH99, it is defective, and
should have been recalled.

If you see SLJ4E, it is OK, and has been fixed.

Intel's "fix" was a quick one, but it affected ALL B2 steppings of these
several chip families.

The "fix" was to disable power savings on the SATA II ports, thererby
keeping these always powered.

Not one of Intel's better ideas, it was a quick fix, and it worked.

Buyers of Intel-based mobos should always look the the "(B3)" suffix on
the products box.

B2 stepping, the earlier release, are defective.

The S-Spec of SLJ4E is the one to have, of the Q65 models.
