Hard drives not seen in BIOS

WIN7 64bit ASUS P8Z68-V PRO/GEN3. I have a SSD on SATA1 with the OS, HDD on
SATA2 with music files and a DVD drive on SATA6. Everything was fine until I
updated my BIOS. Now although everything works OK and the OS sees all
[computer management, device manager etc.] the BIOS only 'sees' the DVD
drive and shows SAT1 & SAT2 as not installed, empty.
I tried installing an older BIOS and the same occurs. It would not accept
the original BIOS as it said it was too old.
What could be causing this?

You could try removing the battery and shorting the reset
pins or leaving the battery out for a few hours.

did you perform step 9?

9 Enter the BIOS Menu and load "Setup Default."

That covers situations, where the definition of the data structures
inside the CMOS storage area, change between BIOS releases.
(It's a tiny area, 128 to 256 bytes of battery-backed RAM in the Southbridge.)

Some of the BIOS flasher tools, have a command line option to
clear CMOS during the flash. And then that's one less step
to worry about.

So one way or another, it can be fixed.

In severe cases, a BIOS may refuse to POST after flashing, and then,
you end up using the "Clear CMOS" jumper (with the power off completely),
to do the equivalent of "Load Setup Defaults". But when the board
doesn't POST, the odds are much higher, that you "bricked it", and
some area of the flash chip, doesn't have BIOS code in it, and the
board is crashing.

The only question inquiring minds have, is why they do that
in the first place (change the data structure definition).
That data structure really should be fixed on the first release
of the motherboard. It's not like the hardware design, changed
between releases.

Thanks for your help. I removed the CMOS battery and shorted the pins. I
then replaced the SSD and HDD with another HDD. The BIOS still doesn't 'see'
any SATA drives apart from the DVD.

In the manual, I see these SATA ports on the motherboard.
Which ports are you testing at the moment ?

I would "fill from the bottom up", to establish that something is working.
The 9172 ports, may have a separate screen or something (not treated the
same as Z68 ports, as 9172 is outside of the chipset).

9172 Ports (2)

Z68 SATA III (2)

Z68 SATA II (2)

Z68 SATA II (2)

Now, while in the BIOS, take a look at section 3.5.4 of the manual.
(I'm looking at the downloadable E6850 version of the PDF manual.)
That's the manual section that covers the SATA Config BIOS page.
There's not much to it - it shows the status of the six Z68 ports
and whether something is detected or not.

If a device is definitely connected, the port is enabled, and
yet nothing is "Detected", then:

1) Check that storage device is receiving power. Use the power
connector off the working DVD drive, if necessary. Listen
for sound of spinning media, on mechanical hard drives.

2) Check any voltage regulator adjustments in the BIOS, that
affect Z68. The "PCH Voltage" is probably a core supply for
Z68 (Southbridge,SATA ports). The VCCIO, I'm not sure what that's
for, as the terminology is rather ambiguous. Could it affect
Z68 SATA launch voltage ? Who knows.

Some of those regulators now, they're extremely accurate, and
not the crappy stuff they used to use. So there's really fewer
excuses for the voltage to not be absolutely correct. While I
did have to adjust one of those voltages on my current
motherboard, it wasn't something affecting SATA ports
at all. (Mine was a RAM stability problem, and needed
Vnb to be cranked up a notch.)

That's about all the user adjustable stuff I can think of.

A number of years ago, mis-adjusting a PCI Express clock frequency,
could knock out SATA ports (because at one time, some of the
clock signals were shared). It was only done that way, for a
generation of boards, until they added a few more clock domains
to the designs. That sort of thing shouldn't happen now.

HTH,

Please clarify...what color SATA motherboard connector --- gray, light
blue or dark blue?

If dark blue, the BIOS would probably not detect the drives connected
here since a Marvel driver is required. However, Windows 7 will detect
these drives since the Marvel driver is installed with Windows setup.
First saw this situation with the ASUS P6X58D's when hooking 6 Gb SATA
hard drives to the Marvel 6 Gb ports.

Same may pertain here.

Yes you are correct. I think when I had my RAID they were in the grey slots
but when I bought the SSD and did not need the RAID I must have incorrectly
put them in the Marvell blue slots. DUH! All is fine now and thanks to all
of you for your help.
