The utility will usually let you back up the current bios; so if flashing fails, you can flash the previous bios back before rebooting.

ok, I`ll go searching for the latest one for my machine.  This morning I found the one for the newer 400MHz model and it`s release date was 1999, so I don`t hold much hope for anything newer for the 300MHz I have.

Does the BIOS setup page usually report what release is loaded on the machine?  Would a BIOS from 1999 report this info?

I'll be loading this up tonight:  ARMADA 1750 6300/T/4000/D/M/1 ROMPaq

My desktop compaq only reports the date; it was from -97 when I got it, and I flashed it to a bios from -99. The boot time nearly cut to half, amazing when they actually update something useful :)

${color #ddd}Battery:  $color ${battery}

Finally got around to this.  And I flashed the BIOS to the latest (nov 1999)

Trying a few things.  

First, I disabled ACPI in the BIOS.  Saw the Battery % for the first time ever.  Showed steady 100% with the cord plugged in or not.  Didn't see any fan, thermal, battery etc modules get loaded.  Fan didn't spin.  CPU temperature displayed 0 zero degrees C.

Then I reset the BIOS to use ACPI.  Battery % shows nothing just like usual.  CPU temperature shows 75C at startup... watching it climb.  6 ACPI modules activated ac, battery, button, fan, processor, thermal.

hmmm... fan never kicked in (like usual).

I have no clue how to use APM instead of ACPI.  What's the difference between ACPI and the APIC boot code?

Thanks so far, what can I try next?  Remember, this machine runs fine under XP.

Here's what I found when I grepped ACPI dmesg:

Code Sample

<4> BIOS-e820: 0000000007ff8000 - 0000000008000000 (ACPI NVS)
<6>ACPI: RSDP (v000 COMPAQ                                    ) @ 0x000fb2a0
<6>ACPI: RSDT (v001 COMPAQ RSDTBL   0x00000001 CPQ  0x00000001) @ 0x07ff8000
<6>ACPI: FADT (v001 COMPAQ CPQB142  0x19991130 CPQ  0x00000001) @ 0x07ff8028

<6>ACPI: AC Adapter [C0CC] (off-line)
<6>ACPI: Battery Slot [C0D6] (battery present)
<6>ACPI: Battery Slot [C0D7] (battery absent)
<6>ACPI: Lid Switch [C108]
<6>ACPI: Sleep Button (CM) [C059]
<6>ACPI: Power Button (CM) [C05A]
<6>ACPI: Fan [C102] (on)
<6>ACPI: Fan [C104] (on)
<6>ACPI: Processor [C098] (supports C1 C2, 8 throttling states)
<6>ACPI: Thermal Zone [C106] (64 C)
<5>apm: overridden by ACPI.


What do the <N> numbers signify?

And I finally found the 'state' files Curaga mentioned in the other post.  My fans are labelled C102 and C104 (I saw it in dmesg above).  When I more state in both folders, I see status: on but fans aren't spinning.  I tried:

Code Sample

echo -n "1" > state
to force it on.


as suggested by Curaga... made no difference.  Thought maybe I could cycle them off and back on, so I tried "0" instead and it also had no effect.  hmmm... I didn't get any errors, and I was using shell as root, but it really seems to me that I cannot change the contents of this file - as if the daemon overrides my changes immediately.

- apm is the power management system that came before acpi. As mentioned, to use it try "acpi=off apm"
