sysdump.c32 is a COM32 diagnostic utility module that will gather certain system-specific data that can be used to help diagnose hardware-specific issues.
The output of sysdump.c32 contains certain system-specific data and should not be shared publicly.
At this time (2011-04-19), sysdump.c32 has two output mechanisms, ymodem and tftp.
TFTP upload is limited to PXELINUX due to the lack of networking in other variants.
sysdump.c32 tftp filename [tftp_server]
If no tftp_server is specified, the one where PXELINUX was loaded from is used.
YMODEM transfer requires a hardware-based serial port on the system running sysdump.c32 and an appropriate cable (often a NULL MODEM cable attached to another PC).
Syntax: sysdump.c32 ymodem filename [port [speed]]
The port defaults to the equivalent of DOS's COM1 and the speed defaults to 115200 bps.
The output of sysdump.c32 is a .cpio.gz file.
