Hi Joe,

IPMI 2.0 supports serial-over-LAN (SOL), so if they implement their
redirected console session via it, FreeIPMI's ipmiconsole tool should be
a suitable cmdline tool equivalent.  Depending on the default setup of
your motherboard, some additional config via FreeIPMI's bmc-config may
be necessary.

As for "remotely mount media", it depends on what exactly you're looking
for.  The following are available for configuration via FreeIPMI's

# Section Chassis_Boot_Flags Comments 
# The following configuration options are for configuring chassis boot 
# Please note that some fields may apply to all future boots while some may 
# apply to the next system boot. 
# "Boot_Flags_Persistent" determines if flags apply to the next boot only or 
# future boots. 
# "Boot_Device" allows the user to configure which device the BIOS should boot 
# off of. Most users may wish to select NO-OVERRIDE to select the configuration 
# currently determined by the BIOS. Note that the configuration value 
# refers to booting *into* the BIOS Setup, not from it. FLOPPY may refer to any 
# type of removeable media. "Device_Instance_Selector" may be be used to select 
# a specific device instance for booting. 
Section Chassis_Boot_Flags
        ## Possible values: Yes/No (Yes = All Future Boots; No = Next Boot Only)
        Boot_Flags_Persistent                         No
        ## Possible values: PC-COMPATIBLE/EFI

        ## Possible values: None/Internal-{1-15}/External-{1-15} (e.g. 
        Device_Instance_Selector                      None
        ## Possible values: Yes/No
        Lock_Out_Reset_Button                         No
        ## Possible values: Yes/No
        Lock_Out_Power_Button                         No
        ## Possible values: Yes/No
        Lock_Out_Sleep_Button                         No
        ## Possible values: DEFAULT/QUIET/VERBOSE
        Firmware_Bios_Verbosity                       DEFAULT
        ## Possible values: Yes/No
        Force_Progress_Event_Traps                    No

        ## Possible values: BIOS-SETTING/SUPPRESS/ENABLE
        Console_Redirection                           BIOS-SETTING

Beyond this, there isn't much in the IPMI spec mounting media.

Hope this helps,
