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.

WARNING

The output of sysdump.c32 contains certain system-specific data and should not be shared publicly.

Use

sysdump.c32 has two output mechanisms, ymodem and tftp.

TFTP

TFTP upload is limited to PXELINUX due to the lack of networking in other variants.

Syntax:

sysdump.c32 tftp filename [tftp_server]

If no tftp_server is specified, the one where PXELINUX was loaded from is used.

YMODEM

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.

Contents

The output of sysdump.c32 is a .cpio.gz file.
