motherboards 654bit 66Mhz / and not with serverworks chipset

["Naert, Hans" <hans.naert@barco.com>]

Hello,

The serverworks serverset chipset HE-SL can't deliver enough PCI64-66
bandwith when you read out of memory,


With the memory read multiple command you get a sustained 300Mbyte/s.

Wich motherboard delivers near 528Mbytes/s,
I've heard that it was possible with the intel 840 chipset, but most
motherboards with this chipset are discontinued.

Are there motherboards with the intel 840 chipset or an other chipset who
support 64bit 66Mhz PCI which are avaible?

I hope that you can help me,

greetings,

Hi,

I am writing driver for ethernet card. Its 64-bit PCI
master.
My PC(mother board) is also 64-bit. I want to map my
card in 64-bit
address space but It does not get mapped in 64-bit
address space.
It always gives 00 for bit 2 & 3 in memory base
register indicating
mapping in 32-bit address space.

How can I map my device in 64-bit address space ?

Thanks

Regards,
Tejendra
