Yes it is. So you change it to Logo=0 to disable it.
Actually this is what I have added to the msdos.sys file after removing the read only protection.
Logo=0 - This setting turns off the silly Windows splash screen during startup. Disabling this will shave a few seconds off your boot time.
Drvspace=0 - This setting turns off support for Drivespace-compressed FAT16 drives. Since no one uses this anymore, it is safe to disable. Disabling it will not only speed up your boot time, but it will also free up some extra resources as well.
Dblspace=0 - Same as above, but this time for Doublespace-compressed FAT16 drives.
DisableLog=1 - This setting disables the log file which Windows creates by default when booting up. Disabling this will shave a few seconds off your boot time, and since no one ever uses the log file for anything anyway, it won't be missed.
AutoScan=0 - This line disables the automatic scandisk that is run if the commputer is improperly shutdown - saving a bunch of time if you are constantly restarting your computer using the power button instead of the 'correct' way. Sadly, however, this doesn't appear to work with Windows Me. - gonna test this in a minute.
Doublebuffer=1 - don't know exactly what this does. Explanations welcome.
My comp definately appears to be booting up faster. I've now got to figure how to edit the system.ini under [386Enh] so I can add:
LocalLoadHigh=1 - This setting tells the computer to load everything the operating system needs into upper memory by default, freeing up as much conventional memory as possible (the first 640K). Microsoft would like us to believe that this no longer effects the system, but they are lying.
DMABufferSize=64 - This setting tells the computer to leave as much memory available for DMA data transfers as possible, speeding up not only the boot process but the system in general.
I've also done some tweaks to my hard drives and system following the advice of the SANDRA 2002 STANDARD program.
