XP logon screen freezes after BIOS upgrade!! Help

Have you tried to restore to a known good point?  Or if that can't be done boot to the XP cd and do a repair?

Well

Last night I tried once again to log into XP before login screen froze.  The fisrt try, it got as far as the desktop icons appearing and then froze.  The second try went a little further and (surprise, surprise) an XP info balloon appears saying New Hardware found: "Intel (R) 82801DBM LPC Interface Controller - 24CC"

Here is a description  of this part of the I/O controller:

"Low pin count interface

The ICH4 implements an LPC Interface as described in the LPC 1.0 specification. The Low Pin Count (LPC) Bridge function of the ICH4 resides in PCI Device 31:Function 0. In addition to the LPC bridge interface function, D31:F0 contains other functional units including DMA, Interrupt Controllers, Timers, Power Management, System Management, GPIO, and RTC.
Note that in the current chipset platform, the Super I/O (SIO) component has migrated to the Low Pin Count (LPC) interface. Migration to the LPC interface allows for lower cost Super I/O designs"

I have no idea why this was found as new hardware, but after one more reboot, everything seems to be working fine.   The only other difference I see is that now the Synaptics intro screen pops up on login.  I did have a Kensington wireless mouse running whose driver replaced the synaptics (I think).  Now the Kensinton driver is nowhere to be found.  Maybe this was part of the problem?  Anyway things appear to be working fine now and dynamic speed switching is back (yay!); but I would like to hear from anyone that may know more about what may have happened.  I have my wife's 5150 yet to do on the BIOS upgrade.

 

Thanks

Have you ever done a clean install on this notebook and if so did you load the chipset driver from Dell?  If not, at the top of this page go to Product Support - Downloads.

flashing/upgrading the bios is always a safe bet but its advisiable not to upgrade the bios till u r having any issue with the system... you can try to restore setup defaults(BIOS) on your system, browse the link below for steps

Why should I restore to XP SP1??  I want the security benefits of SP2 and so far system is working fine.

Unless you are having problems, I would not recommend uninstalling SP2. 

 

I also upgraded my 5150 BIOS from the Phoenix (A06) to Dell A23.

Now widows (sp1) hangs at the login. I'm still waiting for dell to get back to me. I've tried everything that I could think of, and now the steps that cotham describe, with no luck.

I looked thru http://www.bay-wolf.com/ site and found the answer to another question, the change in the way the power indicator is used with A23. That is an excellent site, Thanks Bay Wolf!

It seems to me Dell could be a lot more desrciptive with the readme files included with the bios updates. I had to search for several minutes to find out why ver A36 would not update ver A06!

Yeah, that still aggravates me Dell doesn't put a warning on the D-Series notebook BIOS download pages that you need to use A22 or A23 (model dependant) going from the Phoenix to Dell BIOSes.  Some models are up to A37 already and still no notice to that effect.
