ok, i'll try to help,but no guarantee for success.
i don't know the exact command, i use it not very often.
but if your file isn't much larger than 5 mb you can try the following:
try to find the two lines in the two files and
change the values. possible your max upload-value is at 5mb,
or the phpmyadmin needs longer for the import.
; Maximum allowed size for uploaded files.
upload_max_filesize = 16M
php-myadmin - config.inc.php
$cfg['ExecTimeLimit'] = 300; // maximum execution time in seconds (0 for no limit)
if your file is much larger than 5 mb, than you should use direct
mysql-commands, but i don't know how to use them, so i think you have
to ask in other messageboards.
