Spots, Thanks for the help. What you want to avoid is putting a busmaster PCI card into a non-busmaster slot. BH6 probably has all busmaster slots. Check the manual to be sure; I don't know offhand. Regards, Nick

BH6 probably has all busmaster slots I recall a post in the news groups indicating slots 2 and 3 are busmastering slots on the Abit board. I can not find it now. Here are a couple related posts. ______________________________________________________________ Okay. I'm annoyed a bit. All these reviews about the BH6 never said anything about how the PCI slots, the USB port, and the AGP slot are sharing IRQs in the most inconvenient way. AGP and PCI 1 share the same IRQ, PCI 2 and 3 will use different ones for each, but PCI 4, 5, and the USB will all use the same, single IRQ. This is REALLY annoying, especially when I was installing Win98. What the heck is this setup? I have free IRQs, the hardware should use the free ones first before doubling up things. This is a bit ridiculous, especially when I have a couple PCI cards that don't busmaster and don't want to share. One of the MOST aggraving issues is the way the BIOS assigned IRQ; either auto or "Have these IRQs available for the slots, but just give them to whatever". I love the IRQ assignment on the IT5H; lets you specificly set the IRQ per slot. I want that BACK :). Other than that, good board after I got all the cards worked out. ________________________________________________________________ The BX specification allows for only 4 busmastering PCI slots, all of them off of the Northbrigde chip. On boards like the Abit BH6 with 5 PCI slots, the shared 5th slot closest to the ISA slots is connected to the PCI bus (along with the ISA bus) via the Southbridge chip. The 5th Slot cannot busmaster. I put my 2 voodoo2 cards in PCI-4 and PCI-5, and put my sound card in PCI-1, and my NIC in PCI-2. I left PCI-1 empty since virtually any PCI card that requires an interrupt will share the same interrupt as the AGP slot if it is place in PCI-1 (video cards don't like to share IRQs). You are also correct that the voodoo2 cards do not busmaster, and don't require an IRQ. They are good to put in PCI-5 or PCI-1 on the BH6.
