ACPI3_22_06.PAT      - patch for ACPI.PSD  ver 3.22.06
ACPI3_22_06dbg.PAT   - patch for ACPI.PSD  ver 3.22.06 dbg


DESCRIPTION

ACPI.PSD changes stack for CPU0 during init procedure.
User can set a size of this stack with /ST= parameter in command string.
Unfortunately, no way to tell to ACPI.PSD to leave original stack unchanged.

After this fix, /ST=0 will avoid setting of CPU0 stack by ACPI.PSD.

OS/4 kernel starting from SVN4262 offers big enough stack for CPU0
and does not allow to change it.

To work with OS/4 kernel SVN4262 and newer, ACPI.PSD has to be patched and
/ST=0 has to be added to its command string.

After patching ACPI.PSD will still work with an IBM kernel.

HOW TO APPLY THIS FIX

1. Make a backup of your original ACPI.PSD

2. Copy original ACPI.PSD to the temporary directory.

3. Copy the corresponding ACPI3_22_XXXXX.PAT file to the temporary directory.

4. Run PATCH.EXE ACPI3_22_XXXX.PAT /A

5. Replace the original ACPI.PSD with the patched one.
