My notes, things I have learned, and documentation I have created.

You need to make sure the user is logged out before doing this.

1) Run regedit
2) Go to HKEY_USERS
3) Load Hive # navigate to the ntuser.dat you want to load.
4) Make changes.
5) Unload Hive

I made this modification on an HP DL-360 with dual 1.3 GHz processors, 2GB of memory, and RAID 1 drive (two drives mirrored). It made a huge improvement accessing a directory with a lot of files. According to Microsoft (, ), the setting is increased in Windows 2003. I set in my NT 4.0 server to 16,644.

The SizReqBuf value is stored in the registry under the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
Value Name: SizReqBuf
Data Type : REG_DWORD
Data : 512 – 65535 (bytes in decimal, or 200 – FFFF hexadecimal)
Default : 4356 Specifies the size of request buffers that the server uses.

You can use the softwareupdate command to install updates from a Terminal session. I used this on Leopard.

softwareupdate -i -a #To install all.

softwareupdate -l #To list available updates.

Select Start/Accessories/Clear Storage
Enter 1234
Select Yes

OR

Turn the phone off
Press and hold the dashes to the left and right of the red and green phone buttons.
Press and hold the power button for a couple seconds while holding the buttons above.
Release the keys.
You will be prompted you to clear storage.

From a terminal session:

hdiutil mount filename

hdiutil attach dmgfilename

From what I can tell, this is similar to just double clicking on the filename from Finder.

The image file is then mounted at /Volumes/imagelabel.

base64 -d inputfilename > outputfilename

The dmidecode utility will display the SMBIOS (System Management BIOS) or the DMI (Desktop Management Interface) table. It can be very useful to determine your current hardware and other good information.

To display type options:

# dmidecode -t
Type number or keyword expected
Valid type keywords are:
bios
system
baseboard
chassis
processor
memory
cache
connector
slot

Here is an example:
# dmidecode -t processor
# dmidecode 2.9
SMBIOS 2.3 present.

To page up or down through the list of messages in Mail on a MacBook Pro, hold down the fn and control keys and hit the up or down arrow depending which way you want to go in the list. Note: this does not select them, but at least allows you to scroll through them quickly.

This has been one of the most frustrating problems I have had using the MacBook Pro. I get a lot of mail that just need to scan and delete. It would be nice if I knew how to select them too. In thunderbird, you just use the fn key and the arrows to page down/up. If you use fn and shift, this will also select them. I guess I will have to use thunderbird, if I cannot find a solution.

I have many mail accounts, and I like the way Mail put the Inbox for all of them up top. It makes it easy to get to the unread messages. I would like to try to use Mail, but I need to be able to select too.
