Gateway gm5632e hanging in AHCI controller startup
Hello all, I have a Gateway gm5632e w/Intel (Schroeder Town) G33 Motherboard. (Intel® Matrix Storage Technology) running Vista Home Premium The system is approx. 2 yrs old. I have been away for a couple of weeks and my nephew has been using the pc. Now when I power on the unit I get a hang at the serial ATA Bios screen which detects the HDDs and gives the following: Serial ATA BIOS UPSD SOURCE 8-24-07 .... AHCI BIOS INSTALLED (sometimes it reads AHCI BIOS NOT INSTALLED) The SATA Bios hangs at this screen, so I cannot get into the system bios which loads after this. The only option that I get is to press "CTL + I" to enter the SATA bios and create/delete the RAID Volumes. I am not running RAID on the 2 500 GB, 7200 RPM, SATA II hard drives. I am running them in AHCI. I have done the following: 1. Set the CMOS jumper to maintenance (and got into the system BIOS 1 time) 2. Pulled the CMOS battery. 3. Unplugged the SATA drives 4. Connected a different SATA drive. None of the above have helped me get past this SATA BIOS post. The computer hangs at that screen indefinately. SPECS: Gateway gm5632e Intel (Schroeder Town) G33 Motherboard Intel® Core™ 2 Q6600 quad core processor with VT Each core operates at 2.40 GHz 3072 MB DDR2, 667 MHz Two 500 GB, 7200 RPM, SATA II hard drives Vista Home Premium Any ideas would be GREATLY appreciated T |

Gateway gm5632e hanging in AHCI controller startup
Hi!
I am not running RAID on the 2 500 GB, 7200 RPM, SATA II hard drives. I am running them in AHCI. The two are more closely related than you might think, especially on a system where the "RAID" functionality is a trick of the Intel Matrix storage BIOS. In AHCI mode the SATA controller behaves as an enhanced storage controller and typically will require a special driver for the operating system to see it. This allows you to make use of enhanced serial ATA features and command sets--and it also allows the drivers to "create" features in software that you didn't have before, such as RAID. Since you mentioned changing the hard drive or even attempting to start without one producing no improvement, I would recommend trying to change the operating mode of the SATA controller back to a setting that would enable the emulation of a PATA controller. If you can get back into system setup to make this change, it might help to tell you exactly what is broken. If the system were to work normally, I'd suspect that looking for a newer BIOS revision could help. You would lose the ability to use SATA specific enhancements by doing this, but data transfer speeds should not be affected as the link speed from controller to drive remains high. Try pulling the CMOS battery and leaving the system unplugged overnight. (If you just pull the battery, it may not make a difference because many motherboards will use standby power to keep their CMOS RAM intact.) It seems like this system is very new. Are you sure it's not still under any Gateway warranty? William |
