Machine Check While In Pal; Errors Captured By Rmc; Dump - Compaq ES40CSLP Installation, User & Service Manual

6.7.5.3 Machine Check While in PAL

If a machine check occurs while the system is running PALcode, the machine returns to the
SRM console, not to the operating system. The SRM console writes the following message:
halt code = 7
machine check while in PAL mode
PC
Your system has halted due to an irrecoverable error. Record the
error halt code and PC and contact your Compaq Services
representative. In addition, type INFO 3 and INFO 8 at the console
and record the results.
The info 3 command causes the SRM console to read the "impure area," which contains the
state of the CPU before it entered PAL.

6.7.6 Errors Captured by RMC

The remote management console provides several commands for accessing error information in
the shared RAM. These commands can be entered at a remote console and can be used if you
are not able to access the SRM console because of a system crash. The commands are dump,
env, and status.

6.7.6.1 dump

The dump command dumps unformatted data from the shared RAM. The data can then be
analyzed by service providers. The dump command allows you to dump data remotely from
the RMC. You can also use this command if you are not able to access the SRM console
because of a system crash. For example, you can dump the data from an uncorrected machine
check.
The dump command accepts two arguments:
addr> prompts for the starting address
count> prompts for the number of following consecutive bytes. If no count is specified, the
count defaults to 0.
In the following example, the dump command dumps 5 bytes from address 10.
RMC>dump
Address: 10
Count: 5
0010:13 17 58 11 02 47
In the following example, the dump command dumps 20 bytes from address 3200.
RMC>dump
Address: 3200
Count: 20
3200:20 01 2F 43 01 00 88 00 01 10 00 01 20 00 01 32
3210:00 00 00 00 00 12 20 00 10 20 00 13 00 01 76 00
3220:02
In the following example, the dump command dumps 10 bytes from address 3400.
RMC>dump
Address: 3400
Count: 10
3400:04 08 80 00 00 00 00 00 00 00 00 00 00 00 00 00
