Hi everyone, I have a Gigabyte 6VX7B-4X motherboard that is no longer posting. It gives 8 beeps when powered on. This code means video read/write error. It does this with or without a video card present. At first it only did this when an AGP video card was installed, PCI worked fine. I tried 3 know good AGP video cards and none work in this board. Now it gives 8 beeps at post regardless of there being a video card present or not. I have checked the voltages from the power supply to be sure, and they are all within tolerance. Power supply is tested and known good. This board has BIOS date of 2000,...

Re: SCSI controller problem

well, I've tried everything. You cannot update the firmware unless you have an eeprom programmer according to Adaptec.

All jumper settings are correct as per the drives manual, and the info in this thread. Suppose i'll have to downgrade to a 50 pin drive. that's totally ok for me. But i havent been able to find any. Thanks for helping everyone, I really appreciate it :-)Re: SCSI controller problem...

Re: SCSI controller problem

Thanks for replying! When I move the drives/cable over to the other controller (identical 2490w/uw) the same failure is produced. There are no other SCSI devices on this bus whatsoever, im only connecting one drive at a time. I will check the SCSI bios for the send start unit command. Thanks so much, i'll let you know how it works out. I'm out of ideas otherwise.

Hi there! I have an Adaptec 2940w/uw 50/68 pin controller card in an old machine I'm trying to set up, and i'm having a problem getting the drive to even spin up when it connected to the controller. The drive will spin up with the cable connected to it and not the controller. But not when it's connected to the controller. The drive is a seagate st336607lw u320 10k RPM. The cable is an SE/LVD 68 pin with a terminator on one end. Scsi controller is set to defaults. I have enabled termination power with the jumpers on the drive itself. The drive is connected to the last connector before the terminator...

Hey everyone! I have this set here and the symptom is, the set will shut down after about an hour or so, sometimes giving three blinks of the red standby LED. I know what the code is for three blinks, so I went into the service menu, and under diagnostics is an error under DC Alert, nothing else. I have checked extensively for cold solder joints, and for bad caps with an ESR meter. Nothing jumps out at me.

When the set is running all of the voltages are normal and well within tolerance. When it shuts down, all of the regulators are shut down as well, 12v, 15v, 3.3v stby. Makes it...

Re: New Members - please post your introductions here

Hello everyone! I've used this site before in the distant past and always got great information. Finally joined! A little background about me: I've been in the electronics repair industry for on and off for about 20 years. Mostly TV's and Stereos. Always loved it. Recently started getting back into it, and having tons of fun doing so. I'm fairly well experienced in electronics, a bit of warranty stuff too. I'm hoping I can help out here a bit and learn as well too! Thanks so much to everyone who created this forum, and those...
