Power-On Self Test
Each time you power-on the system, the power-on
self test (POST) is initiated. Several items are tested
during POST, but is for the most part transparent to
the user.
POST checks the following:
To start POST, turn on the monitor and then the
system unit. The following will happen:
1. The IBM Personal Computer logo will appear on
the screen.
2. At this time one of two hot-keys may be used. The
F1 key will cause the system Configuration/Setup
Utility menu to appear. The F9 key will switch the
graphical IBM logo screen to the traditional text-
based system startup screen, which displays BIOS
version and system memory tested. For Personal
Computer Type 2274, the F9 key will only work
after exiting Configuration/Setup Utility.
3. If an error is detected during POST, the IBM logo
screen will automatically switch to the text-based
screen and display the error message or code with
a beep. Depending on the criticality of the POST
error, the system may halt and/or display the
message “Press <F1> to enter to the Setup or
<Enter> to continue...”
If this message appears, pressing the Enter key
will allow the system to attempt to proceed despite
the reported error; pressing F1 will cause the
system Configuration/Setup Utility menu to appear.
