I have a new machine I'm trying to install Centos 5.0 on and I'm not getting very far. The system is 2 dual core xeons (5160, 3.0 GHZ) w/ 8GB ram. It has two 320 GB disks on the motherboard controller (Supermicro X7DAE+), and 8 750 GB disks on a 3ware 9650SE-8ml, pcie (x4) controller card. The 8 disks are set up as two raid 5 volumes (4 disks each). There is a scsi card in the machine w/ nothing attached to it. The graphics card is na NVIDIA Quadro FX 1500 (pci express x16). The intent is to install the OS onto the 2-320GB drives on the motherboard controller (preferrably in a raid 1 configuration). The other disks are for our data requirements. 1)I used bit torrent (azureus on windows) to download the dvd iso for Centos 5.0, and it completed without any errors. I believe it does the checksumming verification automatically. I also ran sha1sum against the image, and it came out fine. 2)I burned the image to a dvd using roxio. No errors. When I couldn't get down the road, I burned another copy with no errors. 3)During the install, I verified the media with no errors for both of the disks. 4)I downloaded the driver for this OS and raid card from AMCC-3ware site and made a driver floppy. 5)I booted the dvd and ran "linux dd" to do the install. Should the graphical installer work on an nvidia quadro fx1500 graphics card? At the present it doesn't appear to work for me, I get hash all over the screen, once X starts. 6)I booted the dvd again and ran "linux text dd". I verified my dvd media without problems, and it reads the driver floppy and loads the 3w-9xxx driver. It asks questions about lang, kbd and timezone. 7)For partitions, I selected custom, created a /boot, /, swap and /home on the first 320 GB disk (it turns out to be sdc, with sda and sdb being the big raid volumes). After the grub section (I told it to put grub on the /boot partition) the screen is blue, and it just sis without any further response (I left it over night, so it should have finished). 8)If I press alt-f3, the last thing I see is: 13:18:16 INFO : Moving (1) to step reposetup 9)If I press alt-f4, the last thing I see is: <5>SQUASHFS error : sb_bread failed reading block 0x6acc <5>SQUASHFS error : unable to read page, block 1aaa0d9, size 9154 8)I'm at a loss as to what to try next, or how to find out what is wrong. thanks in advance for any and all help, -chuck By the Way, a knoppix 3.8 live cd will boot and run fine on the hardware.
