List,
I have attempted to make my own megaraid driver disk for a Dell
PowerEdge 2300. The procedure I'm using is detailed at the end of this
message. In short, I followed samples that I collected after Googling
around. The problem I face is that the CentOS 4 installer can't seem to
mount the driver disk after I have created it. It gives no information
other than, "Cannot mount /dev/fd0", so I don't know where to look to
troubleshoot this.
If there is a documented procedure for creating good driver disks for
CentOS 4, I would very much like to read them; I simply haven't been
able to find any, yet. Otherwise, please review the procedure I have
detailed in this message to spot the flaw. Thanks!!
The procedure I have used to create this driver disk is as follows:
## Log into a machine that is running the 2.6.9-11.EL kernel (e.g.: a
working CentOS 4 box).
# yum install kernel-devel
## Download the megaraid source from the ALMOST useful (doesn't work
because we can't seem to Alt+F2 to get to a bash shell, as described):
