Hi, The CentOS 4.4 installation doesn't work on a Optiplex 745 because it doesn't support the sata controller. Is there a known work-around? (smaller prob: dvi video doesn't work at install time, vga only) If only we had CentOS 5 :-) Cheers, -- Henk van Lingen, Systems Administrator & DBA (o- -+ Dept. of Computer Science, Utrecht University. /\ | phone: +31-30-2534107 v_/_ http://henk.vanlingen.net/ http://www.tuxtown.net/netiquette/

It is worth a try. Fedora 6 will probably run on that hardware. -- MailScanner is like deodorant... You hope everybody uses it, and you notice quickly if they don't!!!!

as far as to CentOS 4.4, a work-around solution for Optiplex 745 ICH8 controller is to add "all-generic-ide" as a kernel parameter during installation. The sata disk is recognised as "/dev/hda" , but the disk speed is actually normal, as the followings: hdparm -tT /dev/hda /dev/hda: Timing cached reads: 4776 MB in 2.00 seconds = 2388.36 MB/sec Timing buffered disk reads: 182 MB in 3.02 seconds = 60.29 MB/sec please dont't forget to add "all-generic-ide" again in grub.conf at the first boot. sles 10 (2.6.16.21-0.8-smp) works well on Optiplex 745. So I think a final solution is using RHEL 5 that we should be waiting at this moment. I ask everyone's pardon for my poor english.
