Thanks for your comments For me, it is important that integrated drivers are compatible. Are existing PCI-e Official Windows 2000 compatible? I have written all motherboards manufacturers. It strikes me that many do not have a pre-sale information service. Most manufacturers respond wondering what model I have already bought. I will make another post to collect official hardware support windows 2000. These are the manufacturers that I have written and their answers: Advantech, Albatron, Aopen, ASUS, AsRock, Biostar, Chaintech, Dell, DFI, ECS EliteGroup, FIC, Foxconn, Gigabyte Technology, iBase, iEi, Intel, MSI, Pc Chips, Sapphire Technology, Super Micro, Tyan, VIA, XFX, Zotac. Hello, I want to buy two ATX motherboards. One has to be compatible with Windows 2000 and other Windows XP. Which is the best model available with minimal drivers for windows 2000 (video, sound, LAN) and which is the best model available with drivers for Windows XP? The Windows 2000 if an ISA slot even better, but if any PCI with a very superior performance dispense with the ISA. A greeting. Advantech: OK The following 4 motherboards accept Windows 2000 (version Pro) AND Windows XP. AIMB-762 AIMB-763 AIMB-764 AIMB-766 For windows XP, if you don’t find something suitable, there is also other options. For Windows 2000 there is no other model. None of them have ISA, but all have PCI. Tell me if you want a quotation on any of those. I will stay available for any further question or inquiry. Albatron: No asked, only micro ATX Aopen: No asked, only mini PC Asus: only telf AsRock: Unable to write pre-sale Biostar: unanswered Chaintech: unanswered Dell: No asked, only PC box DFI: unanswered ECS EliteGroup: unanswered FIC: No asked, no longer manufactured ATX motherboard http://www.fic.com.tw/download/motherboards.aspx Foxconn: how else to respond! As for your enquiry, I suggest you to contact the local reseller or distributor who sell motherboard and PC. They could provide you with a good advice. Thanks in advance! Gigabyte:The recommendation does not have windows 2000 drivers Thank you for your kindly mail and inquiry. Since every one has their own preference, it is hard to define the best motherboard. But we suggest you can consider GA-990FXA-UD5 (rev. 3.0) which supports both Windows 2000 and Windows XP. Since the availability may vary by region, we suggest you to contact the local computer shops or our distributor for further help. Thank you. iBase: unanswered iEi: unanswered Intel: They respond in spanish saying I look in this compatibility list http://www.intel.com/support/motherboards/desktop/sb/CS-008326.htm and then check here http://ark.intel.com/ if the motherboard is ATX. They say no current motherboards for Windows 2000 / XP. MSI: unaswered PCIchips: unaswered Sapphire: unaswered in foro https://www.sapphireforum.com/showthread.php?33696-motherboard-compatible-windows-2000-XP&p=277950#post277950 Supermicro: In this link we can verify compatibility with windows 2000 server I highly suggest our C2SBC-Q if using with Windows XP. Our lab has not verified it with 2000 though. Please check our OS compatibility list for additional motherboards. http://www.supermicro.com/support/resources/OS/C2.cfm Please note that many of these boards are EOL but might still be available from our vendors. Tyan: There’s no Tyan motherboard can support Windows 2000 and XP now. The ISA slot also phase out for years. May be you may consider to install virtual machine to meet your requirement. VIA: No asked, only embedded motherboard Zotac: Thank you for emailing Zotac. Unfortunately, with our current line motherboards the xp/windows 2000 is not supported.
