Thanks guys!!
The solution with the Control+C worked!
I installed the PL1600 with succes with the following line:
accept text apm=off lowres noapic noht nomce nousb nousbstorage skipddc
I also had a few network problems, just as I expected.
I tried to make Windows XP member of the domain (regedit). This failed, but there was a connection and I could use the shares, ping, shh, server-manager, e.t.c.). I found out that there was maybe a problem in Samba because I changed things, expanded the config files and tried to restart the Samba service. The service NMB failed to stop, SMB failed to start.
After this I tried with ifconfig to see what happened on the NIC of the server. Ifconfig froze after calling the command, so there was more.
I searched in lots of forums where lots of guys had problems with the onboard TLan NIC. So I disabled with SmartStart (Compaq server config tool on cdrom) the onboard NIC and added another LAN card (PCI). Everything seems to work pretty well now.
Thank you !!
