Yes, it's possible.
If you search the forums here, there is a tutorial.
Is it possible to install XP on a compact flash card and make it read-only and use the hard drive for swap files etc. or do you have to use Windows XP embedded to make an image file for the flash card. I have heard that Windows embedded is a very tricky program to use.
Thanks for any help
Yup, very tricky to use.
If you're going this route, forget the swap file altogether. Just use enough ram that you shouldn't have to worry. When I had my sys setup in Read Only, I didn't use a swap at all. I have 512mb ram, seems to be fine. Could watch movies, cruise the internet, play music, etc.
Look for threads started by SFiorito.
just remember that flash cards have a limited number of read / write cycles, therefore eventually it will fail.
I used some for an embedded pc for work a while ago and had to replace them all within 6 months, i'd go with DiskOnChip, thats what i replaced the flash with. Yes it is still a type of flash but more durable.
could be cant remember.
