Windows Forum / Windows XP / Performance and Maintainance / May 2006Extremely slow startup and bootvis dies on me with error
I am trying to debug a very slow startup but bootvis dies with an error: "number of logical drives in this configuration is 0, invalid system information". Does anybody what is the reason for this error? Is it because my system is on a RAID? > I am trying to debug a very slow startup but bootvis dies with an error: > "number of logical drives in this configuration is 0, invalid system > information".

Updated: September 19, 2003 http://www.microsoft.com/whdc/hwdev/platform/performance/fastboot/BootVis.mspx About Bootvis.exe Bootvis.exe is a performance tracing and visualization tool that Microsoft designed to help PC system designers and software developers identify performance issues for boot/resume timing while developing new PC products or supporting software. Please note that Bootvis.exe is not a tool that will improve boot/resume performance for end users. Contrary to some published reports, Bootvis.exe cannot reduce or alter a system's boot or resume performance. The boot optimization routines invoked by Bootvis.exe are built into Windows XP. These routines run automatically at pre-determined times as part of the normal operation of the operating system. If you are an end-user seeking to resolve issues for boot/resume performance on your PC, we recommend that you contact the vendor from whom you purchased the PC. For information from Microsoft on specific issues, you can search Knowledge Base for Windows XP product issues related to "resume time." Knowledge Base is a free information service available at: http://support.microsoft.com/?scid=fh;[ln];kbhowto You mean its not supported anymore. I thought it did more than just tune a few things and was useful in finding where the time was spent. I have used it before on a different machine to find that most of my boot time there was too much IO to $mft, which was found to be heavily (7 fragments) fragmented (this is not the current problem because MFT has only two - minimum possible - fragments in this case). How do you find out about where the boot time is spent without bootvis? What is the microsoft supported way of finding this? I did the 'diagnostic msconfig' you mentioned in the other reply. Apart from making it ugly, it actually booted in 3 minutes instead. So, no its not services/startup. My system boots fine, within 15 seconds it says "loading personal settings", shows me my desktop background (but no desktop items), and then it sits there for upto 1-2 minutes before painting my desktop items. This machine is using two WD raptors in raid 0, with AMD 3800 dual core and should fly during the boot. > > I am trying to debug a very slow startup but bootvis dies with an error: > > "number of logical drives in this configuration is 0, invalid system [quoted text clipped - 23 lines] > related to "resume time."

All adapters are configured with static IP so, there is no DHCP involved. What does the system do with network that requires so much time? Its almost as if I can boot with disabled network and put the network enable thing in Startup folder because enabling it takes 2 seconds. does anybody know what commands will enable and bring up a network interface? > You mean its not supported anymore.

I took the workaround path. Downloaded a utility called devcon from microsoft.com and using it wrote two small scripts to disable two network adapters at shutdown and enable them back at restart. Now, during boot, by 20th second, desktop is ready and CPU usage is zero and by 22nd second I am on the net...:-) Thanks for all the help. For others, devcon is available here: http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q311272 You need to get "hardware IDs" for the network adapters from the "Device Manager" by accessing the "Properties" for the network adapter under "details" and selecting "hardware ID" from drop down list. then "devcon disable '<hardware ID>'" to disable the adapter and "devcon enable '<hardware ID>'" to enable it. Startup/shutdown scripts are under start->run->gpedit.msc, Local Computer Policy->Computer Configuration->Windows Settings->startup/shutdown scripts. Have fun!! > > ok, some progress.

Start > Run, copy & paste > msconfig & press Enter. Click on the tab marked "Startup" Uncheck all the items. If the problem no longer persists, then one of the items in the startup is the culprit, you just need to track it down. More here. Run msconfig in the 'Diagnostic startup' mode. If that speeds it up, start restoring services and startup programs in batches till you can identify the offending service/process. |
