+; OS 3.2 has a couple of bugs when booting a 1.3 style boot-block (i.e without EBB_SILENTSTART set)
+; echo stalls until the enter key is pressed, and gibberish spews out in the CLI after our startup-sequence completes
+; This has been reported by other users here: https://eab.abime.net/showthread.php?t=115917
+;
+; lideflash needs to run on kick 1.3 and also 3.2
+; To support both, set EBB_SILENTSTART if kick supports it
