So the first box means "load classic core by default", next one is "don't put the alternative core' menu item to the top of the list", the dialog box with "3" means "The default waiting time in seconds before menu item will be autoselected", under that dialog box there's a checkbox with "Synchronize core version with Windows Update Center when a computer boots up", the long dialog box is alternative core' name for the boot string and the last dialog box with "0" means "increase data addressing limit for user mode applications" (I think it's about that /userva switch). The right button means "Install hotfix" and "About" button is on the left. I hope this'll help. BTW it's almost the same Chinese 2.1 Beta patch with old sys drivers from windows 2003 and there're two additional files - usbstor & usbintel.
