5.6.1 Compiling and Installing	5.6 Additional Kernel Configuration	6 Configuring the isdn

5.6.2 Booting your new Kernel

When your new kernel boots, you should see messages like this one:

isic0 at 0xd80 irq 5 maddr 0xd0000 msize 4096 flags 0x2 on isa

isic0: Teles S0/16, Creatix ISDN S0-16 or Niccy 1016

and a bit later messages like these:

i4b: ISDN call control device attached

i4bisppp: 4 ISDN SyncPPP device(s) attached

i4bctl: ISDN system control port attached

i4bipr: 4 IP over raw HDLC ISDN device(s) attached

i4btel: 2 ISDN telephony interface device(s) attached

i4brbch: 4 raw B channel access device(s) attached

i4btrc: 4 ISDN trace device(s) attached

The first message block tells you that the kernel has identified and initialized your Teles S0/16 ISDN card and the second message block tells that some or all of those pseudo device drivers were installed.
