I have a HP t5740 (Atom processor, 1GB ram, 2GB flash HDD). I got it pre-installed with XP sp2 so I downloaded the new service pack from MS website but it said it didn't have enough disk space to perform the installation.
But according to the system requirements it only needs about 1.5GB so I guess that was some extra working space. So I got XP installation with SP3 integrated and tried to install that. Since it only has one 44pin ATA port (where the flash HDD is), a network plug and few USBs my options were limited. I made an install flash disk using flashboot and it all went fine until it couldn't copy setuporg.exe. The image itself is fine since it worked in a VM.
So, what are my next options? I will try to make a boot usb drive from another image but that still limits me to 2GB. Getting a bigger internal is not an option (limited suppliers, not in stock, ...). Should I attach a bigger external USB drive? If so, will selecting booting from USB in bios work if I have external drive and an install flash disk? Will I need to do a network install? Some other way?
(Note: I know 2GB is really a little space and it should run embedded XP, but I really only need a few hundred MB after I have SP3 on there so unless necessary I don't want to replace the flash HDD. Also it's mounted in a corner with very little space and some replacements I found online won't even fit.)
