Problem with serialmultiportcard

Hi,

took a PC, put in a serial-multi-port-PCI-card (8-port) and installed it with RHEL AS4 (Kernel 2.6.9-5.EL). Redhat recognized the multi-port-card. Here the output of "lspci -vv":

00:10.0 Serial controller: Timedia Technology Co Ltd PCI2S550 (Dual 16550 UART) (rev 01) (prog-if 02 16550) Subsystem: Timedia Technology Co Ltd: Unknown device 4066 Control: I-O+ Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping+ SERR- FastB2B- Interrupt: pin A routed to IRQ 11 Region 0: I-O ports at a800 size=32 Region 1: I-O ports at ac00 size=16 Region 2: I-O ports at b000 size=8 Region 3: I-O ports at b400 size=8 Region 4: I-O ports at b800 size=8 Region 5: I-O ports at bc00 size=8

As you see, linux only find 6 ports... not 8... this is my first problem. How can I tell him, that there are still 2 ports more??

My other problem is, that from the 6 recognized serial-ports, only two works. Only the ports ttyS4 and ttyS5 works. Both internal serial-ports works, too. Here is the output from "ls -ldev-ttyS*":

crw------- 1 root root 4, 64 9. MŠr 15:55dev-ttyS0 crw-rw---- 1 root dial-out 4, 65 21. MŠr 08:47dev-ttyS1 crw-rw---- 1 root dial-out 4, 66 22. MŠr 09:00dev-ttyS2 crw-rw---- 1 root dial-out 4, 67 14. MŠr 10:25dev-ttyS3 crw-rw---- 1 root dial-out 4, 68 22. MŠr 09:01dev-ttyS4 crw-rw---- 1 root dial-out 4, 68 plus 1 17. MŠr 09:20dev-ttyS5 crw-rw---- 1 root dial-out 4, 70 14. MŠr 09:14dev-ttyS6 crw-rw---- 1 root dial-out 4, 71 14. MŠr 09:19dev-ttyS7

dev-ttyS0 anddev-ttyS1 are the internal serial-ports. With the group "dial-out" I enbreastle some non-root-users the use of the serial-ports.

What I have noticed is, that the IO-port-address of the working serial-ports are in the same range. In the output of "catproc-tty-driver" you can see it:

serinfo:1.0 driver revision: 0: uart:16550A port:000003F8 irq:4 tx:8208 rx:0 RTSDTR 1: uart:16550A port:000002F8 irq:3 tx:14 rx:738 CTSDSR 2: uart:16550A port:0000B400 irq:10 tx:61 rx:0 3: uart:16550A port:0000B800 irq:10 tx:189 rx:64 4: uart:16550A port:0000AC00 irq:10 tx:976 rx:1745 fe:11 brk:3 CTSDSR 5: uart:16550A port:0000AC08 irq:10 tx:81 rx:2385 fe:14 CTSDSRCD 6: uart:16550A port:0000B000 irq:10 tx:118 rx:5 brk:2 7: uart:16550A port:0000B008 irq:10 tx:16 rx:0

There you can see, that ttyS4 and ttyS5 have the IO-port-range 0000AC0x... but I was not able to change the IO-port-address of the other serial-ports with "setserial".

Anybody an idea?!
