- Hi,
- there is only the choice between 'normal polling' and 'alternate polling'.
- You should use 'alternate' only, if you get errormessages like 'Watchdog
- timeout'. But if you are using a SCSI disk, your diskaccess is very sloooow,
- if you choose the wrong IRQ during installation. But it's so slow then that
- you should noticed this before (1-2 seconds pause after ls).

- Cheers, Ecki
