Author: wmb Date: Tue May 24 23:12:36 2011 New Revision: 2220 URL: http://tracker.coreboot.org/trac/openfirmware/changeset/2220 Log: TCP - Reduced the TCP receive buffer size to keep the advertised window smaller, thus preventing the other end from sending-ahead more data than small-buffer network interfaces can handle. This makes HTTP reads work much better on OLPC XO-1.5 and 1.75 systems, especially over WLAN.

Some word not in ofw.c32 ?

Hi, I want to write some application when I go into the interpreter, I follow these tutorial: http://www.openfirmware.org/1275/practice/ But when I learn the first one: 16 Color Text Extension, I met problem. I want to have a try on foreground-color, but it seemed can't run and returned some information: ok foreground-color Tried to access instance-specific data with no current instance ok I have this one on my laptop /packages/terminal-emulator Did I miss some thing when I read the documents? I'm pretty new with Open Firmware, are there easier tutorial for beginners? references: http://www.openfirmware.org/1275/practice/ http://www.openfirmware.org/1275/proposals/index.html -- Hu Songtao works as an English Teacher in weekends Skype: idisblueflash Beijing, China

boot with usb disk met:ofw.c32: not a COM32R image
by 胡松涛 22 May '11

22 May '11

hi, When I try to make a usb boot disk. I get : ofw.c32: not a COM32R image I did this for a x86 cpu and my system is Ubuntu 11.4, syslinux is 4.02. I guess maybe the script generator is just for syslinux 2 years before. And syslinux changed a lot in two years, maybe form COM32 to COM32R. And ofw.c32 maybe is just a COM32. Any one can fix it? -- Hu Songtao works as an English Teacher in weekends Skype: idisblueflash Beijing, China
