Hello, It's me again ;) I have not accounted for a newer feature in the Linuxes (poll call on devices) and I need a file from the source three of something really fresh. The file /usr/src/linux/drivers/char/mem.c will do fine. If any1 would like to email it to me, thanks. 2.1xxx and above is interesting... Of course 3.xxx is ok too (Eli ?) ;). tia, Peter
