a 64 mb flash stick boots fine;
a 512 mb (a 1gb, a 2gb, etc.) NOT !
- probably a motherboard problem.
at boot, the smaller stick is recognized by the BIOS
as USB-HDD, the bigger ones as USB-floppy -
the opposite of what would be 'logical' to expect.
both sticks were formatted FAT under ms-windows and
both received a new MBR written by the SLITAZ ' ~ make-
usb-boot-utility ' under SLITAZ-live cd .

any ideas for a workaround ?

p.s. : much praise for SLITAZ`s sleekness and leanness -
it fits my needs for a fast-to-boot 'internet appliance'.
+ this forum interface is super !
