+
+You must have at least 32 megabytes of RAM to use the Debian installer.
+
+You should have space on your hard disk to create a new disk partition
+of at least 256 megabytes to install the base system. You'll need more
+disk space to install additional packages, depending on what you wish
+to do with your new Debian system.

+
+ [ Press ENTER to boot the live system ]
+
+Or:
+
+ "live-failsafe"
+ Start the live system in fail-safe mode.
+ "install"
+ Start the installation using the normal installer.
+ "expert"
+ Boot into expert install mode, for maximum control.
+ "rescue"
+ Boot into the installer rescue mode.
