    Subject[PATCH for review] [4/48] i386: DMI_MATCH patch in reboot.c for SFF Dell OptiPlex 745 - fixes hang on reboot
    Date

    From: James Jarvis <James.Jarvis@ed.ac.uk>

    The following patch enables reboot through BIOS on the Dell Optiplex 745
    Small Form Factor base, on which reboot hangs. The larger form factor does
    not require this, hence the match on DMI_BOARD_NAME.
