I built my serial cable exactly as laid out in Sergey's blog:
Scan down for Serial Console.
He gives PuTTY settings also. 115200 is right.
For me, this is a dead reliable way of seeing the console. Never seen a dropped bit.
What kind of cable are you using?
I connected the same pins as Sergey (besides looping 4-6 and 7-8).
I'm still not getting a useful session.
I plugged in my USB to Serial connector and using minicom I was able to connect to the Galileo. One quirk, if the Galileo is booted, and you connect to the serial console, you will need to press enter before you see anything in the console.
commands I used:
It could be a problem with your serial cable. I initially built my own cable, and that worked but was ugly. Since then I have bought one off of amazon.
You are losing bits...
At this point I would try it on a different PC (easiest) then a different serial converter and cable (harder but most likely problem).
One last thought - how long is your cable? I try to keep cables around 3 feet.

It's probably less than three feet, actually. I'll have to try the other options you (and chofrock) suggested. I'll report back if I get anywhere.
A simple reboot of my PC got things going. I've got a perfect tty session open now!
Now, is there any way to get the BIOS window?
You probably mean something like BIOS settings e.g. date/time, boot order, etc? There's nothring like that, because there's no BIOS in Galileo, it's based on UEFI. You can get into the UEFI shell by hitting F7 right after power on (you'll see a prompt in the serial console), but that's not the same as BIOS settings.

That's right. I would specifically like to be able to boot to a usb .iso image. Is there no way to do that?
You can get to the UEFI shell as I mentioned above and try to boot from there. Or get past that - to the grub, which is what UEFI starts next, and try it from there.
But AFAIU right now booting anything but linux is unsupported and indeed doesn't work.
So it would depend on what you have on that USB drive I'd say
Thanks. It's Linux we're after. In fact, assuming I couldn't boot and install directly, I tried Thomas Faust's recipe for building a SD image (Build debian Linux distribution for Galileo board with debootstrap) and I've had at least initial success. My next step is to get the Intel mini PCI-e WiFi going.
Thanks for all the help!
You're welcome :-)
Depending on your WiFi card, you may get it working right away by using the SD card image available in downloads section. But it all depends on your broader goals - there are quite a few opportunities by now (Yocto-based LSB+eglibc+SDK Linux, uclibc-based "SD card" image, somewhat working Debian one, you can always build your own with some effort).

I have the LINUX_IMAGE_FOR_SD_Intel_Galileo_v0.7.5 files on the SD card I'm booting from - it successfully gave me wireless access in my pre-Debian sessions - but it doesn't seem to be picking it up now. In fact, I had to apt-get install wireless-tools pciutils iw manually in Debian.
Do you have any idea why that is?
