An application for BOOT from usb any ISO - Ventoy

<< < (2/2)

Doug Bissett:

--- Quote ---Dave - I attach an image of how far the boot goes. You can see that the usb drivers are loaded.

Loaded. yes. Operational, no. The USB drivers normally take a few seconds (a LONG time, at computer speed) to finish initializing. During that time, there is no access to USB devices. Since OS/2 doesn't have any way to wait for initialization, it just assumes that the media went away (or the required file(s) aren't there), so it throws the error.

Some machines have a setting in the BIOS, something about "USB hand off", where the BIOS will continue to operate USB devices, until the driver takes over. That may work, sometimes, but could be very timing sensitive. The switch would need to happen exactly between file fetching, or the switch could happen while the file is being fetched (probably not a good thing).

I found an external usb device that can take an iso file and present itself as an external DVD.
The device is based on the idea of the isostick.

I have an isostick, but use it for other operating systems.
The isostick would not work for OS/2 installs.

I installed a 120GB ssd in the enclosure.  I copy the ISO file to the device.  Then set the device to be a DVD, and plugged the device into a usb socket.  I was able to install with no problems.

The only complaint I have so far is the poor "jog button" interface to select options on the device.  The manual is sparse and does not explain in detail this "jog button."

I use this device on ArcaOS, FreeBSD, Windows, and various Linux distributions.
I never have to make another DVD disk.

I have a Zalman with CD emulator. It isn't very easy to use due it takes some time to enable the emulator and on some desktop PC, the time is greater than the time between USB is powered on and boot start .... on disk due the emlator isn't ready fast enough. For best use, have an USB port with always power on  ;)

Sandra Asja Eickel:
After researching, I found a kind of improved successor of the Zalman device:

I got mine for €85,00 from Amazon.

It remembers the selected CD image and up to four virtual Floppies/Sticks/removable HDDs and has a keypad instead of a jog dial. Only if you use AES encryption, an always-on USB port is recommended, otherwise it would be hard to enter the password before the computer boots.

I have a Samsumg SSD QVO (don't buy this series with four bits per cell) which works inside a PC, but refused to operate in two other external enclosures. In the IODD-2541 it works.

Greetings,
Sandra-Asja
