.TH "gptsync" 8 "2008 July 24" "Debian" "rEFIt" .SH NAME gptsync \- GPT partition table to MBR partition table synchronisation .SH SYNOPSIS .B gptsync [\fI\-q\fR] [\fI\-t\fR] \fIdevice\fR .SH DESCRIPTION .B gptsync reads the GPT partition table on \fIdevice\fR and synchronises the legacy MBR partition table with the GPT partition table. The MBR partition table can hold only 4 partitions. .PP Legacy bootloaders or operating systems that do not support GPT require an MBR partition table; this is typically the case when using GRUB or LILO on an Intel-based Apple machine. .SH OPTIONS .TP \fB\-q\fR Do not print any message, do not prompt to modify the MBR. .TP \fB\-t\fR Truncate partitions starting or expending beyond 2 TiB (MBR limitation). Default is to ignore such partitions. .SH AUTHOR \fBgptsync\fR was written by Christoph Pfisterer.
