Figure When the microprocessor performs a memory read, the data address is used to find the data in the cache. If the data is found a hit , it is read from the cache memory and no external bus cycle occurs. If the data is not found a miss , an external bus cycle is used to read the data from system memory.
If the address of the missed data is in a cacheable address space, the data is stored in the cache memory and the remainder of the cache line is read. When the microprocessor performs a memory write, the data address is used to search the cache. If the address is found a hit , the data is written to the cache and no external bus cycle is used to write the data to system memory. If the address of the write operation was not in the cache memory but was in cacheable address space, the data is read back into the cache memory and the remainder of the cache line is read.
If only data in this address range is already in cache memory and the address range is written to, the cached line is invalidated and is read again from RAM in which the BIOS is shadowed in. ThinkPad Z System Board The clock circuitry uses 14 bytes of this memory; the remainder is allocated to configuration and system-status information.
This bit is set to 1 by a power-on reset. Interrupt 1AH is the BIOS interface to read and set the time and date; it initializes the registers in the same way that the setup program does. If set to 0, it indicates that the current date and time can be read.
Bits 6—4 These bits identify which time-base frequency is being used. Nickel metal hydride or lithium-ion battery pack The large- capacity battery pack extends the operating time of your computer, further enhancing its portability. Audio with 3D Stereo Sound Your computer is equipped with internal audio record and playback capabilities including 3D audio from just two speakers. When you enable the 3D stereo feature, sounds will appear to be generated al around you, even though only two speakers are used.
For more information on using the audio function, see the Online User's Guide. ThinkPad Modem The ThinkPad modem enables you to send or receive data and faxes over a telephone line.
TrackPoint with Enhanced Controls Your computer has an enhanced TrackPoint function that enables you to make selections merely by pressing on the TrackPoint. A new. Functional Highlights center button converts the TrackPoint into a scroll control- ling device or a magnifying glass on the screen. Chapter 3.

The two memory slots accept dual inline memory module DIMM options. Identifying the Hardware Features System Status Indicators The system-status indicators on the computer show the current status of your computer by their on or off states and colors g and orange.
Each indicator is identified with a symbol. The follow shows the location and the meaning of each icon:. System Status Indicators 1 2 3 4 5 6 7 2 1. Blinking orange The battery pack needs to be charged Orange The battery pack is being charged. Do not enter suspend mode or power off the computer when this indicator is on.
You enable or disable the keypad by pressing and holding Shift thekey, and pressing the NumLk key. All alphabetic characters A-Z are entered in capital letters without the Shift key being pressed. You enable or disable the Caps Lock mode by pressing the Caps Lock key. Thekeys can be used as screen-scroll function keys. The cursor cannot be moved with Arrow thekys.
Not all application programs support this func- tion. You enable or disable Scroll Lock mode by pressing the ScrLk key. This indicator is on when the computer is on and not in suspend mode.
System Status Indicators Distinctive Functions of Your Computer Your computer has unique keyboard functions and utility programs for easy configuration. Pointing, selecting, and dragging all become part of a single process you can perform without moving your fingers from their typing position. The TrackPoint consists stick of aon the keyboard and click three buttons below the keyboard.
Movement of the pointer on the scree is controlled by the amount of pressure you apply to the nonslip on the stick in any direction parallel to the keyboard; the stic does not move. The speed at which the pointer moves corresponds to the pressure you apply to the stick. The function of the cl buttons depends on the software you are using.
Getting Familiar with Your Computer Distinctive Functions of Your Computer Stick Left click button Center button Right click button If you are not familiar with using the TrackPoint, these instruction will help you get started: 1.
Place your hands in the typing position and press gently with either index finger on the stick in the direction you want the cursor to move. Pressing the stick away from you moves the cursor up the screen; pressing it toward you moves the cursor down the screen. You can also move the cursor side to side by pressing sideways. Do not use TrackPoint until the cursor stops moving. Mouse pointer Cursor Stick. Make sure to check his site for detailed install instructions.
A lot of times, sound won't play correctly it sounds reminiscent of Max Headroom. Doing the following magic invocation as root seems to fix it:. Sound doesn't automatically re-enable itself after a suspend or hibernate. Charles Wright has a handy little script to re-enable it after coming out of hibernation:. Charles recommends muting the speakers Fn-Backspace first, because if the microphone is enabled you'll get feedback. I downloaded the driver osslinux39h I am running Red Hat 5.
Trying to get the sound working with SB16 drivers that came with the kernel only resulted Sound Blaster Pro compatible sound 8 bits. The procedure was as follows:. It should work from there. You can rerun soundconf to change the parameters chosen in steps 2 and 3 above.
The serial port is disabled by default in the TP The TP can only run one of the serial and infrared ports at a time. The easiest way to enable the serial port is to go into Windows 95 and use the config tool there. In general, you'll need to fiddle with the sound configuration as well.
See Thomas Hood's ThinkPad page for more details, if you're brave. Another common problem is inserting PC cards containing serial devices like modems. The PC card conflicts with the built-in serial port even if disabled.
Modem functions require the cooperation of the DSP and host software. There is currently no Linux driver. I hear rumors that IBM may be considering doing one. These rumors are even more plausible now that IBM is officially supporting Linux. Get in touch with them and let 'em know what you think. I found the link from a page maintained by a disgruntled Aptiva owner. Thomas Hood reports that he has been in touch with someone who may be able to write a modem driver for Linux.
He needs proof that there is a demand. I did! However, judging from this email , the "ACP" modem is no longer being actively developed, so it's unlikely that IBM will do the development themselves. Still, nothing to keep them from just releasing the code and letting the community finish the job. You will need to recompile your kernel for power management to work. Here are the settings for APM I used:. A number of other people have reported slightly different configurations working for them.
