OK its 4 months down the road and I am re-visiting tc on my thin client and the good news is I got it to boot from a CF connected to the 40 pin disc header on an adapter.
So I booted my laptop to tc+ disc and then plugged in the CF but in a USB adapter. I then installed core to the CF using /dev/sdb [I think]
This went well and completed without error - I used 'showapps noswap waitusb=5 kmap=uk' and chose hdd install and ticked for kb extensions
When completed I shutdown laptop and removed CF then installed it in the thinclient
It boots ok with one error I cant catch but I still want to do what my original post suggests.
So, starting with persistence - how the hell do I find my disk id or device name?
Have tried fdisk -l and it just falls back to the next line?
cat /etc/fstab doesnt actually show any discs and doing fdisk on /dev/hd[a,b,c] or /dev/sd[a,b,c]
doesnt work either [no device msg]
The first thing I need is persistence and I think I need to specify where my tce= lines
Any help appreciated!
