Have two Gigabyte GA-7VT600 1394 motherboards. Neither will POST with a XP 2600+ Barton. Have four chips (two OEM and two retail) and chips work fine on other motherboards. Have tried other cases, i.e. different power supplies. Have google'd and checked forums...appears problem is related to the new low power Barton chips.
Per Gigabyte web site, similar motherboard GA-7VT600 (non-1394) required BIOS update to support Barton:http://www.giga-byte.com/Mothe...uppo...S_GA-7VT600.htm
Unfortunately, no BIOS update supporting Barton offered for 1394 mobo:http://www.giga-byte.com/Mothe...uppo...T600%201394.htm
I have latest F4 BIOS for GA-7VT600 1394. With Barton chip, machine fails to POST and issues wailing French ambulance siren sounds for a few seconds before powering itself off. Was able to POST with a 1.3 Duron and verify BIOS version and confirm that motherboards are not bad.
