slax 5.1.8 on USB - cannot use copy2ram
I have installed slax 5.1.8 to a USB flash drive.
When the system boots, I do not get any time delay in which to type 'slax copy2ram' as I do when booting directly from the CD.
I have tried holding down a key to try sending a character via the keyboard repeat function, as this approach solved the same problem with an earlier version of slax, but this no longer seems to work.
Is there a way in which I can invoke a splash screen delay to emulate the operation of the CD and allow me to pass parameters to the kernel on boot?
Any help much appreciated!
