So the only option is to install in Turkish and later use the Regional & Accessibility options to change language.
Sorry, I do not agree with you.All
the information to install P2008/P2009 in the available languages with a USB device is in [this Wiki page]
And as of October-8-2009 it's also possible to use Puding (0.2-7-3) in P2009 to make the USB device as shown in [this topic]
This last option has the benefit that you also get the Language selection (and other) option screen.
Sorry if it seems I haven't explained my point very well.
In fact, I refer ONLY to installation of Pardus from a USB key which has been prepared as follows:
i) Use Unetbootin and a Pardus iso to burn a USB install key
ii) With any editor, modify the /boot/syslinux.cfg file on the key so that the second stanza reads
menu label Pardus Usb
kernel /boot/kernel mudur=livedisk vga=791 splash=silent quiet
For the Pardus_2009.iso, the USB install key prepared using this technique worked perfectly for me on my EeePC 901 and the F2 option to select English as the install language was available.
However, for either Pardus-2008.2-Canis-aureus-International.iso or Pardus-2008.2-Canis-aureus.iso, a USB key prepared by this method, did NOT present the F2 option to select English as the install language.
In this case, and THIS CASE ONLY, the only remaining option was to install in Turkish and, subsequently, use Regional & Accessibility to change the language from Turkish to English.
Sorry for the confusion.
