<P><FONT SIZE=2>Brian,</FONT>
</P>
<P><FONT SIZE=2>Thanks for the response. Here is the additional info I have, including </FONT>
<BR><FONT SIZE=2>how my power management is set up in the BIOS along with what the </FONT>
<BR><FONT SIZE=2>documentation says the /proc directories should be. As I said in the </FONT>
<BR><FONT SIZE=2>original message I only have the /proc/acpi directory which the </FONT>
<BR><FONT SIZE=2>documentation doesn't mention. Hopefully, someone locally has played </FONT>
<BR><FONT SIZE=2>with ACPI. I'm thinking of going to Mandrake 9.0 and abandoning RH7.3, </FONT>
<BR><FONT SIZE=2>but this Gigabyte GA-7VKML motherboard isn't listed under the compatible </FONT>
<BR><FONT SIZE=2>motherboards. I forgot to mention in the original message that I had </FONT>
<BR><FONT SIZE=2>already updated to the latest BIOS available from Gigabyte.</FONT>

<BR><FONT SIZE=2>> |</FONT>
<BR><FONT SIZE=2>> |Here's what I've done/found so far:</FONT>
<BR><FONT SIZE=2>> |</FONT>
<BR><FONT SIZE=2>> |System Description:</FONT>
<BR><FONT SIZE=2>> |-------------------</FONT>
<BR><FONT SIZE=2>> |</FONT>
<BR><FONT SIZE=2>> | CPU: 1.2 MHz Duron</FONT>
<BR><FONT SIZE=2>> | MEM: 128 MB</FONT>
<BR><FONT SIZE=2>> | DISK: 40 GB (20GB Win98SE/20GB Linux)</FONT>
<BR><FONT SIZE=2>> | MB: Gigabyte GA-7VKML</FONT>
<BR><FONT SIZE=2>> | BIOS: AMI</FONT>
<BR><FONT SIZE=2>> |</FONT>
<BR><FONT SIZE=2>> |</FONT>
<BR><FONT SIZE=2>> |What I've done:</FONT>
<BR><FONT SIZE=2>> |---------------</FONT>
<BR><FONT SIZE=2>> |</FONT>
<BR><FONT SIZE=2>> |1. Installed RH7.3 (kernel-2.4.18-3)</FONT>
<BR><FONT SIZE=2>> |2. Upgraded to kernel 2.4.18-5</FONT>
<BR><FONT SIZE=2>> |3. Upgraded to kernel 2.4.18-10</FONT>
<BR><FONT SIZE=2>> |4. Rebuilt kernel turning off APM and turning on ACPI</FONT>
<BR><FONT SIZE=2>> | Here is excerpt from .config file:</FONT>
<BR><FONT SIZE=2>> | CONFIG_PM=y</FONT>
<BR><FONT SIZE=2>> | CONFIG_ACPI=y</FONT>
<BR><FONT SIZE=2>> | # CONFIG_ACPI_DEBUG is not set</FONT>
<BR><FONT SIZE=2>> | CONFIG_ACPI_BUSMGR=y</FONT>
<BR><FONT SIZE=2>> | # CONFIG_ACPI_SYS is not set</FONT>
<BR><FONT SIZE=2>> | # CONFIG_ACPI_CPU is not set</FONT>
<BR><FONT SIZE=2>> | CONFIG_ACPI_BUTTON=m</FONT>
<BR><FONT SIZE=2>> | # CONFIG_ACPI_AC is not set</FONT>
<BR><FONT SIZE=2>> | # CONFIG_ACPI_EC is not set</FONT>
<BR><FONT SIZE=2>> | # CONFIG_APM is not set</FONT>
<BR><FONT SIZE=2>> |5. Downloaded and installed acpid-1.0.1-1.i386.rpm</FONT>
<BR><FONT SIZE=2>> | Verified it's running and in a sleep state.</FONT>
<BR><FONT SIZE=2>> |6. Enabled every possible BIOS ACPI restore option.</FONT>
<BR><FONT SIZE=2>> |7. Looked at /proc directory, found there was a /proc/acpi</FONT>
<BR><FONT SIZE=2>> | directory, but nothing related to acpi under /proc/sys</FONT>
<BR><FONT SIZE=2>> | as the documentation (acpi_howto.txt) suggests. As experience</FONT>
<BR><FONT SIZE=2>> | has shown, documentation doesn't bare any resemblance to what</FONT>
<BR><FONT SIZE=2>> | I'm seeing.</FONT>
<BR><FONT SIZE=2>> |8. Found /proc/acpi directory contains only "file" called events.</FONT>
<BR><FONT SIZE=2>> |9. Found there is no option in the kernel config file to turn on</FONT>
<BR><FONT SIZE=2>> | or off Sleep mode.</FONT>
<BR><FONT SIZE=2>> |</FONT>
<BR><FONT SIZE=2>> |HELP!</FONT>
