Hi,

I'm a bit thick when its comes to these, this is the first one I've had!
I have a big problem with a SN85G4 (Version 1.0) I've got a Sempron 3000+ 64 installed which comes up as AMD Hammer unkown model, so I need to flash the bios as its still running on the factory bios but here's the problem; It posts fine goes through drive list, IRQ settings then it freezes if I try to boot from ide hd or dvd. If I try to boot from floppy it doesn't even see it. I get the following message if I boot with no disk in the dvd;

NVIDIA BOOT AGENT 191.034
PXE -E61 : media test failure, check cable
PXE -MOF: exiting Nvidia boot agent
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER

I've tried replacing the ide cables, the hd, dvd, memory, graphics card, same result. I've tried the jumper settings on the ide devices, I can get into the bios but can't find much to help there, the hard-disc and dvd are recognised though and I have reset the CMOS. I bought this off somebody who claimed it was fully working, any help would be great as this is/was to be my christmas present! :confused:

Thanks again,

John
 
It sounds like you just don't have the floppy enabled in the BIOS or that your boot order is messed up.

1. OK, let's start with this:
http://www.xpcbios.com/index_eng.html

This guy makes CD images so you can flash your BIOS from a CD in case you don't have a floppy (or in your case you can't get the floppy to work).

2. Is your floppy light on all the time? If so, then your cable is flipped.

3. Another very real possibility is that your BIOS would need to be upgraded before your system will be stable.

4. Are you sure you have your heatsink mounted properly. Go into the BIOS and see what the CPU temperature is under the PC health section (or hardware monitor).

I'll edit this shortly with more suggestions.
 
Thanks for the reply, the floppy drive does work now but the problem i've got is after maybe 4 secs of reading either the floppy, dvd drive or the hard-disc the whole system locks up. So I can't flash the Bios, install windows or do anything really!
I think the CPU is fitted ok my temps are about 40 on the cpu and about 30 in the case.
Thanks again,

John
