IBM ThinkPad 820 PowerPC Information and Software

System Type: 6040 "Wiltwick" (earlier systems)

System Type: 7247 "Wiltwick" (later systems)

Released in 1995 alongside its bigger brother the ThinkPad 850, the ThinkPad 820 was offered as a 'lower cost' model that did not contain the web cam and a few other things nerfed such as the RAM capacity with a 32-bit controller.

Both system types 6040 and 7247 are for the same system board, IBM changed the system type for some reason for later units (and the default configuration was adjusted as well to better specifications).

Booting Into Service Mode

Below are the excerpts from IBM's removed articles on booting the 850 and related machines into service mode for AIX:

When booting a PowerPC into Service mode, cd0 or rmt0 must be before the hdisk in the bootlist. If not, change the bootlist at boot time. On some models, you can set the machine to use a default bootlist that includes both cd0 and rmt0. If a bootable CD or tape is in the CD-ROM or tape drive, the machine will boot from this device.

For most of the newer PCI-based models, selecting the default bootlist, with a bootable tape or CD loaded in the machine, causes the system to automatically boot from that device. Generally, the next menu on the screen asks the administrator to define the system console.

For all machines discussed here, if you are using a graphical terminal, you will use a function key such as F5. If you are using an ASCII terminal, use an equivalent number key such as 5. Use the numbers across the top of the keyboard, not the numbers on the numeric keypad. On ASCII terminals, the icons may not be displayed on the screen; the number can be pressed between the second and third beeps, the second beep being a series of three clicks.

PCI machine-specific information

The following systems all use the F5 or 5 key to read from the default boot list, which is written into the system firmware:

MODEL       7017       7024       7025       7026       7043       7137
-------   -------    -------    -------    -------    -------    -------
TYPE      S70        E20        F30        H10        43P-140    F3L
          S7A        E30        F40        H50        43P-150        
          S80                   F50        H70        43P-240           
                                           B80        43P-260          

On these machines, use 5 (on the keyboard, not the keypad) if you are using an ASCII terminal. On a locally attached graphics console, use the F5 function key. The F5 or 5 key must be pressed just after the keyboard icon or message is displayed on the console. If you have either a 7026-M80, 7026-H80 or a 7025-F80, then the 5 key will be the default whether you have an ascii or graphics console.

The following systems use the F1 key to enter System Management Services mode (SMS):

MODEL       6040       7042       7247       7249
-------   -------    -------    -------    -------
TYPE        620        850        82x        860

You should be in an Easy-Setup menu. Select the Start Up menu. Clear the current bootlist settings and then select the CD-ROM for choice 1 and hdd (the hard disk) for choice 2. Select OK. Insert the CD-ROM and select the EXIT icon. The machine should now boot from the CD-ROM.

The following systems use the F2 key to enter SMS:

MODEL         6015       6050       6070       7020       7248
-------     -------    -------    -------    -------    -------
TYPE          440        830        850        40P        43P

Select Select Boot Device from the initial menu on the screen, and then select Restore Default Settings from the list. Press the Esc key to exit all the menus, and then reboot the machine. The system should boot from your bootable media.
