Very Computer

I'm trying to install the release 4.7 in a Pentium 100 with a PCI graphics
card and a ISA ethernet card (IO=0x300, IRQ=5).

I have created the two disks (kern and nfsroot) and I have started the
installation.

When I arrive to the visual  kernel configuration it says that there are 7
conflits, but when I remove the network cards that doesn't apply, the
conflicts dissapear.

It's OK until now.

When I press the Q option and save the configuration, the system starts to
show the detected devices :
.....
ata0: at 0x1f0 irq ....
ata1: at 0x170 irq ...
pci0: <Cirrus Logic GD5434 SVGA controller> at 12.0

and the system stops in that line, the floppy light is on, but it doesn't
continue.

What can I do?
May be a problem of the graphics card?

Thank you for your help.
