I have been using a new ECS K7S5A main board for two months and I was fairly satisfied with it. I had some initial misgiving but I stayed with it.
1. Although it has on-board sound it seems to not have any kind of DOS Sound-Blaster emulation for older games like Duke Nukem.
For this reason I stuck in my Turtle Beach Allegro sound card.
2. I just put in an Adaptec AHA2940 SCSI host adapter to drive an HP C5100A photo scanner. I can not get the board to distribute IRQs properly to get all PCI devicecs to work at the same time.

Here are the wierd things the board does with PCI:
A. There is no way to designate IRQs for legacy applications.
B. It does not like to reassign IRQs 3 and 4 if the COM ports are disabled.
C. It likes to assign all the PCI devices to one or two IRQs.
D. It is impossible to assign IRQs manually.
