I bought an old micro-ATX MS-6198 ver.1.0 equipped with Intel Pentium 3 800 CPU and 256 Samsung SDRAM memory.BIOS is AMI ver.1.6 (last AMI for this MB). I tested it with two different HDD,30 and 80 GB with Xp Pro,but,after initial booting,where everything seems to be OK,system restarts. I tried some different BIOS settings,but nothing happened. I remarked that with the 80 GB HDD the restarting is almost immediate,while with the 30,Windows Xp runs few seconds more. I tried also to reload Xp from the CD,but the system stopped any times while charging the drives. Can you help please? Thanks in advance.
