Set a Realtek 8019AS network card to half duplex - HOW?



Hi!

I have a cheapo ISA Realtek8019AS card (worst Ethernet card ever built
etc.). Also, I have a cheap 10Mbit hub. The 8019AS sadly thinks that it
should operate at 10Mb Full-Duplex, featuring transfer rates around
100kB per second... (with collision rates going over the top, of
course). 

Apparently, there's no MII interface, so I can't use mii-* tools (tells
me 'operation not supported') ne2k-diag can't be told to just set the
card to half duplex, so I'm a bit stuck now.

Anybody knows how to set that card to half duplex mode?

Thanks VERY MUCH if anybody reveals a solution
