I'm building pxe-booted kiosk systems using pxelinux 3.09 and linux kernel 2.6.14. I noticed a discussion on this list that 3.09 supports a 511 character command line but that the kernel would need to be patched to access it beyond 255. How can I patch the kernel to do so?

SYSLINUX 3.11-pre5 is hereby a bug fix release candidate. If I don't receive any problem reports, I will release it as-is on Tuesday, August 30. http://www.kernel.org/pub/linux/utils/boot/syslinux/Testing/ -hpa

Hi, I just replaced the pxelinux.0 of some 2.x version by pxelinux.0 vers. 3.0.7. Some of the PXE Clients refused to boot thereafter (just stopped after reading the config file). I noticed that the APPEND line was too long. Is this intentional? What is the maximum length of the APPEND option line? Thanks, Thomas

changing i386 COMMAND_LINE_SIZE to 1024 attached is a simplistic fix to change kernel's command-line size from 256 to 1024, tomatch capability in syslinux 3.08. It seems to work. Is this all there is to it ? One of the reasons I did this was to figure out what extra options are appearing, and why. b4 extending: (the...

I''m having problems with my Dom0 kernel command lines being truncated, and I want to increase the command line size. They currently default to a maximum size of 256 bytes and I want to increase that to 1024 bytes. I changed the #defined variable COMMAND_LINE_SIZE in 3 places in the 2.6.18 kernel from 256 to 1024, but it had no effect. I''m aware that I''m actually passing my command line to Xen which then passes it to the Dom0 kernel, but I discovered the #define GUEST_CMDLINE_SIZE which is already set to 1024. Can somebody tell me how...

Hi, in syslinux-386, I think I've found a problem in com32/lib/syslinux/load_linux.c that leads to cmdline being truncated unnecessarily when e.g. linux.c32 is used. The patch below fixes the problem for me. But I don't know, whether the patch is safe in all cases. I tried to reproduce the logic found in runkernel.inc, but I might have missed something. So, feel free to tell me
