AW: [CentOS] Problems with installation

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?

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.

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.
