Can syslinux be upgraded to support more then 4 serial ports? Could syslinux be configured to auto probe for the first serial port? Ubuntu 6.6.1 boots and can find the card at port ttyS4 and ttyS5. Voyage (debian) linux reset the pci serial card and assigns it to ttyS0 and ttyS1 A few weeks back I asked about a boot loader with ttyUSB support. It was pointed out that a USBserial stack would be very bloated. So I purchased a pci serial IO card. ON boot up the card is configured to port 4 to avoid conflicts with the on board hardware. Ubuntu 6.6.1 boots and can find the card at port ttyS4 and ttyS5. Voyage linux (debian) reset the pci serial card and assigns it to ttyS0 and ttyS1 syslinux and extlinux can not see the card at boot up. Can extlinux be configured to auto probe and use the first serial port it finds? serial -1 115200 Thank you for your hard work, Nicholas A.

This should be consistent across boots unless you change the hardware configuration. You *may* have to turn "PnP aware OS" to "Off" in your BIOS settings (this setting is really "Skip initialization of cards I don't recognize.") -hpa
pnp off - change I used dmesg to find the default address and serial 0xe800 9600 worked great. Thank you. Do you know how I force the kernel to use the same address? ----- Original Message ---- From: H.

Peter,
It looks like Hp has done a lot or work in this aria,
http://kerneltrap.org/node/4351.
If you have trouble with your output, use console=ttyS0 console=tty0, or
console=uart,io,0x3f8.
I will report back my tests. Can we add the results to the syslinux docs?
console=uart,io,0x3f8
console=uart,mmio,0xff5e0000,115200n8
I'll also add getty's on all my serial ports to make sure I get a login
after a kernel upgrade.
Thanks for the help,

Now when I think about it, I think the syntax is something like
console=uart:io:0xe800 but you have to check the details.
