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):

## Done making the Driver Disk.
## Insert disk 1 of the CentOS 4 install set into your Dell PowerEdge 
box and reboot the machine.
## At the CentOS 4 install prompt, insert the Driver Disk into the 
machine and type:
 > linux dd

## Error:  Cannot mount /dev/fd0 ?!
