About SOYO SY-6BA + IV, Slot1 and BX chipset, with HD controller with Highpoint HPT366 chip and RAID.
I managed to boot with a PII 300 Slot1, PC100 32MB RAM and VGA AGP with maybe 4MB ATi 3D Rage Pro Turbo chip.
Obviously the BIOS messages due to low battery (changed before booting) appear, I press DELETE to enter the BIOS, and I enter to have a look if I notice abnormal values, there is something strange but nothing important, the frequency is indicated in 200MHz, but actually in the start screen you see the right frequency 300MHz, obviously this CPU has FSB 66, if I set 100 and it started it would go to 450MHz, this thing was easy to do in Celeron Mendocino, with a I even got there to 112 of FSB, but in this Mb I am not interested in overclocking, otherwise everything is ok by pressing F1, it continues until the operating system message is missing.
This is because I have not yet connected a hard drive or IDE-CF adapter and memory card, however I assume everything is working normally.
The MB was repaired some time ago by replacing two electrolytic capacitors with recovery capacitors of the same capacity and voltage, those used are 1000uF 6.3V OSTs (normally having new ones I would have used Rubycon or other branded capacitors), unfortunately the original ones were swollen and with high ESR, one 13.8ohm and the other 23.1ohm and then they were at a loss (undetectable capacity).
Currently there is no sound card and if necessary that LAN, I have to choose from the ones I have but I think I use PCI cards.
