Hello,everyone in this list ! I have a PC with old motherboard: Gigabyte-GA686BX (440BX - based) with PII-450 & 768M SDRAM. And I should build a Samba-server for workgroup with this hardware. As all you know, 440BX has only UDMA33 capability. I would like to use newer harddrives on this machine (2 x IBM 30G/7200rpm/UDMA100). So, now it's time to decide: what kind of UDMA100-to-PCI adapter should be purchased. The main target is to build ***bootable RAID1 array*** under RH7.1. I'm not sure about reliability of Promise-binary-only drivers, and AFAIK GPL driver did not work for RAID1. So, since it will be a production server, using of standart Software RAID is preferred. Also I should say, that internal (440BX-based) IDE controller will stay for CD-ROM / CD-RW drives, but not for any HDDs. So drive map should be (I hope): UDMA100 : 2 masters (IBM's HDDs, one per channel); 440BX-IDEcontroller: CD-ROM and CD-RW, both masters on separate channels. What can you recommend ? I'm thinking about Promise Ultra100 (not FastTrak100 - or is it useable as ordinary (not RAID) UDMA controller?). Maybe any HighPoint controllers or ASUS (relabeled Promise , AFAIK) will be the better choise ? Thank you for replies! With best regards, Alim V. Baidjanov
