Almost right. No booting from this card is required.

Have you tried pressing ctrl-A when the Adaptec display appears in the boot process? It's been a while since I looked at the Adaptec SCSI BIOS settings, but I know there's an setting to suppress the ctrl-A prompt on booting. I never changed it, but always ass*u*me*d that turning this off would still allow one to enter the BIOS settings without the prompt.

When the system boots, there is not the usual 'addon card' operation where the card detects drives, displays it on the screen, then continues to POST. The system simply boots like the card isn't there. As long as you can boot from another device, the card is happily recognized and works flawlessly once an OS is running. I've looked into resetting the configuration on the card, etc... I just think in this case the card may be a lower end card used for secondary addon storage only without the option to boot... --Tim ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Does it have an option to enable/disable bios in the card setup like other ataptec cards?

[CentOS] Adaptec SCSI Card 2930LP supported by CentOS 5.x?
Hi, for a specific application we need a low-profile SCSI card (PCI) with external 50pin connector. I thought about getting an "Adaptec SCSI Card 2930LP". However I was not able to find any usable information about wether this card is supported by Linux/CentOS 5.x or not. Does anyone have this card working with a CentOS 5.x machine? Alternatively: Are there any linux-supported low-profile PCI SCSI cards with 50pin connector which are supported by CentOS 5.x and which you can recommend?
