<html><body><div style="color:#000; background-color:#fff; font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12pt"><div>Hi,</div><div>I'm in the process of dusting off an old Geode GX1 thin client I have and upgrading it to coreboot v4. I had no problem building a new coreboot image (v4 is SO much easier than v2), but I'm having an issue with SeaBIOS and option ROMs. <span style="font-size: 12pt;">Since this is my first time working with SeaBIOS, I need a bit of help to bring this together.</span></div><div style="color: rgb(0, 0, 0); font-size: 12pt; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; background-color: transparent; font-style: normal;"><span style="font-size: 12pt;">I built a PXE ROM for the onboard NIC, which is a NatSemi DP83815 (DEV/DID 100b/0020). I've tried both an iPXE image built from scratch, as well as a GPXE ROM from
rom-o-matic. I added the ROM with cbfstool as documented at coreboot.org, and also added a bootorder file that lists the NIC first. However, when SeaBIOS calls the ROM, nothing seems to happen. See below, where it tries to boot from the ROM but fails almost immediately. It boots successfully from the local disk after the ROM returns. Any pointers as to what the issue is are appreciated.</span></div><div style="color: rgb(0, 0, 0); font-size: 12pt; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; background-color: transparent; font-style: normal;"><span style="font-size: 12pt;"><br></span></div><div><br></div><div style="background-color: transparent;">Start bios (version rel-1.7.2.1-0-g88cb66e-20130924_201442-test-f14)</div><div style="background-color: transparent;">Found mainboard DTRI WBTG</div><div style="background-color: transparent;">Ram Size=0x07de0000 (0x0000000000000000
