Boot from USB stick
« on: May 19, 2023, 01:37:51 pm »
Boot from USB stick is not difficult now.

How to:
  1)  choose a letter for your boot USB stick - better use unused (for ex. F:);
  2)  create Compatibility Volume, Primary Partition on your USB stick with chosen letter;
       (it could be complicated but it is another matter)
  3)  format  F:  /fs:hpfs   or  format  F:  /fs:jfs   (both working fine)
  4)  sysinstx F:
  5)  you may need to create fresh installation  on HDD F: (I don't know another way how to change a disk letter in all settings, say, from C:  to  F:)
  6) copy everything from HDD F: (change letter for it before copying)  to your USB stick F:
  7) now you can boot from USB stick

!!!!  Once you have chosen and set letter for USB stick -  never change it  -  the letter is stored in a few places and not all programs change it properly.

This way I created  stick  to boot to command prompt  but one friend of mine made a full functional system (boots till desktop).

Prerequisites:
   - USB drivers from Lars Erdmann (at least usbdrv249); Lars, thank you very much for your drivers with this amazing ability.
   - OS/4 kernel (at least 6217).

Feedback is welcome.

Hi  OS4User
  6) copy everything from HDD F: (change letter for it before copying)  to your USB stick F:

What do you recommend for copying all from the HDD to the stick? A simple copy command or some other copying tool?

I used FC/2 because it is the most convenient tool for me to work with files.
