Hi Please check this http://www.syslinux.org/wiki/index.php/Hardware_Compatibility#USB_related_problems It could help with boot speed issue. 08.01.2015, 05:21, "Hermès BÉLUSCA - MAÏTO" hermes.belu...@sfr.fr:Hi all ! In this video :https://drive.google.com/file/d/0BzFtJhksW7viRDRVMzluTnFjMlU/view?usp=sharing(with strong French accent, sorry :P, and it was my first attempt at making a video with a camera in one hand while doing the other things with the other hand ^^), I show an attempt to create a hybrid-USB key by configuring freeldr to load either a livecd (shown in the video) or a bootcd in ramdisk. Many remarks are in order: - there’s a crash when booting the bootcd image, early in phase 1 boot in Io (can be reproduced locally on vbox for example, with similar freeldr.ini parameters that I show in the video).- the whole story consists in loading a ramdisk, so I avoid all the USB-related storage problems we could (and certainly) encounter if I used the USB key more like as we do for our current livecds, i.e. permanent reads to the removable device.- a ROS livecd that can be removable (in the sense that one can use another cd to test something, while ROS is still running) should be done with some kind of hdd image file instead, that is then loaded in memory (so that we can then read and write to this virtual drive).- something weird happens when freeldr loads the livecd iso in memory: first it takes 7 minutes to just try to open the iso file, and then 7 other minutes to load the iso proper. This problem needs to be investigated.- we still report strange dates when listing files from the livecd (at least when it is mounted as ramdisk), see the video.- finally, when using Standard PC (non-ACPI) HAL, I don’t really think we reposition HDD heads into “sleep position”, because when I switch PC power off with the button I can hear the HDD making the noise of the heads quickly going back to sleep position, whereas I don’t think this should happen if the heads were being already in the correct position before I switch power off (when using the “shutdown” command of FreeDOS, the other OS I have installed in the PC, the noise isn’t produced). Cheers,Hermès. PS: I keep the right to remove the video at any time if I notice misuses. And it’s not an official video (even if I was playing around with Windows Movie Maker with the ReactOS logo during the first seven seconds, and with the website links at the end) !!,___Ros-dev mailing listRos-dev@reactos.orghttp://www.reactos.org/mailman/listinfo/ros-dev -- Best regards,Alexander Rechitsky aka Jeditobe ___
