Base System Device two are missing My Dell Inspiron E1505 laptop is missing two driver Base System Device is what they are called. I have downloaded every driver on the site for this laptop yet I still am missing these two. Best Dell Base System Device Device Driver Support — DriverFinder. If you do manual update drivers, you need to know every device technical specification for install the right drivers.

I have a Dell Inspiron E1505 that I've upgraded with a T5600 Core 2 Duo CPU, a pair of PC5300 2gig SODIMMs and a 500 gig hard drive. I downloaded the 'media refresh' X17-59465.iso updated x64 ISO of Windows 7 and made a bootable USB stick to install it. Partway through installing it popped an error about not having a driver. Restarted, it boots off the hard drive, gets to the Starting Services screen then pops another box saying it can't install Windows.

I know other people have installed x64 Win 7 on this exact model with a Core 2 Duo CPU upgrade so what's the trick to making it work? I also know it will use around 3.5gig of RAM. Would going back to the 1.5gig of PC4200 that was in it get Win7 to complete its install? Unplug all other HD's and peripherals, Boot into BIOS setup, reset to defaults, save changes.

If an EFI BIOS you'll need to decide if you want If otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install: Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Windows update automatically found the SD card part and downloaded the driver for that, so why not the Memory Stick driver? The official Dell support pages for the E1505 and 6400 only has 32bit XP and Vista drivers. This page has the whole lot for Vista x64 and earlier, back to Windows 2000. But note the complete lack of any Ricoh x64 drivers. Found one that works here This has been a PITA since 1995 where Windows knows these details about the hardware but hides it all from the user with the generic 'unknown device' bullshoi. It only adds hours and hours of time to working on computers hunting for the right drivers. Computer and software manufacturers have been doing this sort of bleep for the 30 years I've been working with them, probably did it before and will very likely continue to keep on doing it.

The more obscure the driver, the less likely it will be provided by installer or Windows Update. I've shown you how to maximize the chances. There will always be one or two devices which need drivers or tracing.
