I'll try to install CentOS 4.3 for X86_64.

Do you have an idea how I can find out which device causes the keyboard to freeze? I'm not able to watch at the consoles without input device :-( Is there a list which single devices/buses I can disable to probe for?

I tried to boot with dd=nfs:<ip>:<path> too. But at the moment the installer tries to load megaraid_sas BEFORE network is reachable :-( So I think I need noprobe the device which freezes the keyboard _and_ in addition I need to find out how to noprobe for any SAS-Device (storage controllers). Does the option scsi=noprobe exists?

Hi all,

I try to install CentOS 4.3 for X64_64 on a new Dell PowerEdge 2950. I have two problems:

After booting from CD I pressed 'return' to start installation (BIOS-support for USB-keyboard works). After probing the hardware my USB-Keyboard is not working anymore. Dell removed ALL PS/2-Interfaces so I have to use USB. When I start installation with 'linux noprobe' the keyboard still is working and the installation starts.

unfortunately, the usb support at install time is quite limited, what you might need to do is find specifically what h/w is causing the installer / keyboard to freeze up, and disable probe of that device /bus only. the noprobe, by itself, will tend to stop the installer from looking at anything - perhaps, not the desired result.

After the installation starts it tries to load the storage drivers. In the case for this hardware it tries to load megaraid_sas. But it can't load the driver without an error. The installer just says:"loading megaraid_sas" for hours and hours (the complete last night). When I start

with 'linux noprobe'

I'm able to look at another console (alt+F2) and can try 'lsmod'. The output for megaraid_sas is 'loading' and not 'live' (again: for hours).

you will need, as Jim pointed out already, the drivers from Dell for this - also, i see you have an issue with the /dev/hda instead of the /dev/fd0 coming up, one workaround for this is to convert the drivers into an iso format and burn that to CD...

What Ver / Arch of CentOS are you installing here anyway ? in most cases the installer will ask for which device has the Driver Disk ( you only need to boot with linux dd ). the only time that it wont ask, is when it can only find one device which might contain the driver disk ( perhaps with the noprobe the fd0 is not being detected at all ). if you have network, DD=http://somewhere/ should work as well, from the boot line.

I've not actually used one of these machines, so just sharing some ideas that might be worth trying.

HTH
