Op Coolinfo vond ik wat stuff over Abit's ZM6:
The ZM6 motherboard is ABIT's second Socket 370 offering -- the first was the BM6, an Intel BX-chipset-based product. The Intel ZX/100 chipset was used in the ZM6. What differences are there between the BX and ZX chipsets? The primary differences are that the ZX will only support 256Mb of memory (as opposed to the 1-gigabyte limit for the BX), as well as a limit of 4 bus master PCI slots. Other than that there are no differences between the two chipsets. Are those limitations significant? Read on to learn more.
