In http://www.anandtech.com/showdoc.html?i=1250 (Intel 440BX 133MHz Motherboard Roundup (June 2000)) is said that only the 'Gigabyte GA-6BX7+' through an PAL (programmable array logic) chip and the 'Microstar BXMaster' through an PCI arbiter chip have 6 PCI Bus Master capable slots. But Tom at http://www6.tomshardware.com/mainboard/00q2/000518/cubx-01.html says that the Asus CUBX also has 6 PCI Bus Master capable slots. So has the CUBX also such a 'special' chip to support 6 PCI Bus Master slots, or does the CUBX only support 4 PCI Bus Master slots?
