All the USB ports have full power the instant the machine is powered on, always and unconditionally.maurizio.dececco wrote:The USB port is simpky switched off.
Yes, thank you. That was exactly what I was asking.maurizio.dececco wrote:I think the original poster question was a little different: for example, the x61s cannot boot from an USB *powered* DVD because the power on the USB connection is not present at the beginning of the boot; the power in the USB connection is switched on after testing for USB boot devices. For this reason, on the x61s you have to connect the USB DVD player to an external power supply *only* when you want to boot from the DVD or CD-ROM.Maurizio
LOL, that's great! Just after posting I happen to go out and buy the LG GP08LU10 and I'm soooooo relieved to find out that you can boot an OS from it.maciejs wrote:I happen to have a LG GP08LU10 External Super-Multi DVD Drive (http://www.lge.com/us/computer-products ... 08LU10.jsp) which is USB powered and I can confirm that X200s can boot from this drive. The drive actually comes with two USB cables, one for data transfer and one for power and it is noted in the manual that secondary cable MAY be required for the drive to function properly. But I used this drive to install OS several times and was only using single cable so I'm guessing that secondary cable is only needed for burning disks and not just reading them.
I plan on doing that several times. Well, I wiped them both so quickly I don't even remember the letters of these drives but they are there so you can do a factory restore of your OS. I have no plans for restoring my laptop to its factory state as it was simply useless straight out of the box with preloaded Vista Business and god only knows what other software. The whole system was VERY SLOW to the point of being unusable - I'm amazed that some people actually use their preloaded OS...ajdedo wrote: 1) What did you do with partitions 'Q' and 'S'? Are they needed if I install XP over my factory installed Vista?
It's hard for me to tell as this is my first external optical drive. It's not bigger/heavier than my sister's discman (which she got few years back) and I guess it's portable enough to throw it into your bag/backpack and hit the road. I don't really use it to be honest and bought it only as a last resort since I use optical drives just as I use Windows - only when there is no other way. I install my main OS (see sig) using USB flash drive and installed Windows only so it's there when I will have no other choice one day.ajdedo wrote: 2) Is it me, or did you find the LG drive slightly bigger and heavier then expected?
Just for the record: you don't have to delete these partitions to do a clean install of whatever OS you please. Just leave them where they are and partition your drive "around them". This way you loose several GBs on your disk but retain a way to reverting back to original OS for whatever reason that might be...ajdedo wrote: First I learned partitions "S" and "Q" are useless, just as I suspected, but wanted to confirm. I always do a "clean install" any chance I can. That way I can use my computer problem free for at least a couple months before it slows down again.
I don't know that much about Windows retail but I vaguely remember that if you have a valid Vista license you have a right to downgrade to XP Pro. But it could've been just for Vista Ultimate and furthermore only for retail copies. Laptops are generally sold with OEM licenses. I think they were also offering this "privilege" as a paid add-on.ajdedo wrote: Second, that comment about having a valid license is interesting. My laptop came with Vista and a Vista sticker on the bottom. What do I need to do to get a valid XP licence?
AFAIK you can install any version of Windows via USB as long as there a optical drive attached at the other end of a cable (-; But seriously, only way I can thinkg of right now that you could "install" Windows from USB stick would be to use some sort of disk cloning tool (such as ghost) with a USB boot disk. They obviously don't throw around the copies of OS X on flash drives (not in retail anyway) so I would dare to say that linux is rather unique with this feature. At least among certain OSsajdedo wrote: Third, Install from a USB Drive is a WAY better idea then from a DVD. Is that unique to linux, or can XP be installed from a USB Drive too?
In theory installing from flash drive should be no different from installing from CD if you build it right. Not sure about Vista but you can install older Windows from a folder on a hard drive running MSDOS and booting a flash drive usually emulates a hard drive. The problem you're likely to have though is just that: the flash drive becomes the primary hard drive and I don't think Windows will install on any other drive (certainly it won't boot if the bootloader is not on the primary drive even though it might work with the Windows folder on another drive). Even if it does install, once you remove the flash drive the drive letters will be changed and Windows won't be able to find itself since it would be looking for some drive letter other than C: (values such as SystemDrive=D: and SystemRoot=D:\Windows would be in the registry). One way around this might be to create two partitions on the drive before installing Windows and use a utility like Ghost's GDISK to 'hide' the first partition. Then install to D:, unhide the first partition, remove the flash drive, reboot, run Windows recovery console to put the bootloader on the now unhidden drive which has become C: . I haven't tried this yet but I think it should work.maciejs wrote: only way I can thinkg of right now that you could "install" Windows from USB stick would be to use some sort of disk cloning tool (such as ghost) with a USB boot disk.
