Hi guys - bit of an odd one.

I recently stuck a 60gb Samsung 470 in my Asus 1225B (specs are AMD C60, 4gb DDR3, AMD 50m). I reinstalled Win 7 x64 and used the latest drivers from the Asus site.

Performance in Windows is fine - read and write speeds are roughly where I'd expect them to be (about 230 read, 170 write). OTOH, boot performance is pretty feeble. It's faster than the HDD it replaced, but takes a good 20 seconds longer to boot than the Vertex 2 in my aging Dell lappy (which is running in sata 150 mode!).

I can't figure it out - I tried AMD's chipset drivers, which helpfully stuck the drive in SATA 150 mode (no improvement to boot speed, obviously). It's a fresh install of windows and the drive is properly aligned... The only think I can come up with is the CPU bottlenecking things (which seems unlikely even for something this low end).

Any ideas?
 
Sorry, should have said also running latest bios. I'm talking purely Windows loading time (POST takes about as long as you'd expect, so it's not like it's hanging trying to detect the drive).
 
AHCI's enabled in the bios (amazed it's an option, considering how limited it is) and in the registry.

I just ran bootracer on the netbook, which gives me 34s to logon and 1.11 to desktop. Must admit I'm stumped... Performance on the desktop is generally as snappy as I'd expect (for a netbook).

Boot speed is a lot slower than the laptop (which is running a T5550, 4gb DDR2 and a Vertex 2e in SATA 150 mode). Haven't run bootracer on it, but boot speeds on the laptop are much closer to my desktop...
 
Sounds like a possible OS corruption, or more likely a missing/corrupted driver. Laptops/netbooks use many non-standard devices and drivers, so it's important to get the EXACT ones for your specific machine (ie don't rely on generic versions that "work" on a whole series of machines). As well as driver issues, BIOS settings could drastically affect boot times, as the BIOS looks and waits for non-standard or non-present devices.

If you're feeling brave, you could check the bootlog (ntbtlog.txt in Win7) but you have to enable logging first. Here's a quick guide, or Google a better on :

You could also try analysing Event Viewer, which sometimes catches errors from the boot sequence :

Again, feel free to Google a better/more in-depth article. It can be a nightmare trying to find the one important line in 300 lines of meaningless (to me, anyway) log/script/waffle that Windows spews out. Be patient, and good luck!


PS Check around the Asus user forums, someone else is bound to have the same problem, and may have found a solution.
