Yes, you are right. The driver lists my card as:

lnc0 at 0xffe0-0xfff7 irq 9 drq 0 on eisa
lnc0: PCnet-32 VL-Bus Ethernet controller, address 00:00:1a:40:38:02

The lance driver in Linux also sees the card as VL-Bus controller.
I guess that this is caused by a bug in AMD 79C970 chip.

Thank you very much for the advice. I have found 
the jumper "HB ENA/HB DIS" (not described in the NIC
installation guide) whose factory setting was "HB DIS". After 
changing the setting to "HB ENA" my ethernet card works fine. 
The driver has stopped displaying error messages.

By the way, the 'shutdown -r' command doesn't reboot the computer
if I'm using PCI ethernet card. It writes:

syncing disks... done
Rebooting...

Then it blanks the screen and dies until I press the reset button.
If I exchange the PCI card for the ISA based NE2000 controller
the 'shutdown -r' command works fine. This seems to be a hardware
problem because the MS-DOS behaves similarly (doesn't reboot on
Ctrl-Alt-Del). I'm using TMC PCI54PV motherboard (ISA/VESA/PCI) 
with a P54C/CT 90 MHz microprocessor and OPTI chipset 
(82C596/82C597/82C822).
Any comments or advice would be greatly appreciated.
Thanks in advance.
Regards,
Alex
