that would be a problem. nm > ttyS0 is at 0x02F8 and using irq3 according to the setserial manpage the kernel does not detect actual com port paramters it just sets them according to what it thinks is right. [from the man page] During the normal bootup process, only COM ports 1-4 are initialized, using the default I/O ports and IRQ values,as listed below. The "standard MS-DOS" port associations are given below: /dev/ttyS0 (COM1), port 0x3f8, irq 4 /dev/ttyS1 (COM2), port 0x2f8, irq 3 /dev/ttyS2 (COM3), port 0x3e8, irq 4 /dev/ttyS3 (COM4), port 0x2e8, irq 3 [end excerpt] I find it best to go into the BIOS and hardcode the com port settings to what is accepted as "defaults" (see above) and not let the system just pick an irq and i/o address. On my system the kernel says: ttyS00 at 0x03f8 (irq = 4) is a 16550A ttyS01 at 0x02f8 (irq = 3) is a 16550A ttyS03 at 0x02e8 (irq = 3) is a 16550A then i use setserial to change the config to: /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3 /dev/ttyS3, UART: 16550A, Port: 0x02e8, IRQ: 2 (in this case IRQ2 is the same as IRQ9 something else i learned during the configuration of this machine for 3 com ports) nm >I'm so relieved that I have my network working finally (after nm >spending ALL DAY yesterday on it) that I'm really not looking nm >forward to messing with eth0. Depends on the card. most cards hafve a dos based config tool that let you change the options on the card itself, to take it out of PnP mode and slap it into non PnP. Even if your card does not have such a tool if it is using a commonly used chipset you most likely can go to another vendor's utilities and use them. I did this with a generica NE2000 compadible card, i went and grabbed DLINK's dos utilties to card code my card to an acceptable address and irq. Also if possible go to the bios and hard code the COM settings, and tell the bios that IRQ3 and 4 are set to non PnP mode(not all bios's have this feature, AWARD does as does AMI). And tell the machine to reload the PnP data, this option is also in the bios, could be labled "Reset Configuration Data" or "Update NVRAM" or something similar. nate ----------------------------------------[mailto:[EMAIL PROTECTED] ]-- Vice President Network Operations http://www.firetrail.com/ Firetrail Internet Services Limited http://www.aphroland.org/ Everett, WA 425-348-7336 http://www.linuxpowered.net/ Powered By: http://comedy.aphroland.org/ Debian 2.1 Linux 2.0.36 SMP http://yahoo.aphroland.org/ -----------------------------------------[mailto:[EMAIL PROTECTED] ]-- 12:47pm up 107 days, 29 min, 6 users, load average: 1.89, 1.73, 1.69
