Hi Rich,
I ran the sorter.sh script, (but I had to get it from
http://tinycorelinux.net/3.x/release/src/kernel/sorter,sh-----> the github link didn't work for me---> I got this sorter.sh with "wget", and then did a "chmod 775 sorter.sh" and then ran it--->seemed to be okay), so that was the last thing I did in your big list (I didn't make an initrd or anything), on power down I made a backup, and now tried to re-boot.
On boot-up, I wasn't given a choice between the old kernel and the real-time kernel, I just saw a little "boot: " prompt echoed to screen, and then eventually, off it went with the real-time kernel.
But, during boot-up, I did see an error,
modprobe: chdir (2.6.33.3-rt19-tinycore): No such file or directory
Failed to open /dev/ramzswap0: No such file or directory
swapon: can't stat '/dev/ramzswap0': No such file or directory
And then the boot-up process continued momentarily, but then hung-up on "Loading Extensions", by hung up, I mean it just gets stuck there, and doesn't go any further.
Any ideas what I did wrong ? I used the "bzImageRT1" naming convention for the kernel and am using the "regular" initrd (tinycore.gz) for both the "regular" and "real-time" kernels.
Thanks,
David
