this came up some time before - it works if you uncomment the other
types wd etc. - but this is only a hack
t
hasn't Dmitry Kohmanyuk said ? ...

> I know there can be some problems with supplied nb8390.com since it's configured

> The card is set to port 0x300, irq 5. The boot program is set to port 0x300.
> I have patched source to insert some debug printf's, and found that it
> fails testing for 8-bit card, and hangs when testing for 16-bit card.
