I can find and use HP mini 210-2177nr with 32-bit / 64-bit BIOS Software with Graphics GMA 3150 for 32-bit or 64-bit software, with 32-bit/64-bit N550 CPU and Chipset NM10. At HP it does not explain its 32-bit/64-bit BIOS Software, yet once you start to install it, it does explain its 32-bit/64-bit Software, so thankful for 32-bit/64bit BIOS Software. Depending upon what Hard Drive or Solid State Drive I use for 64-bit Software, SATA 2 Solid State Drives I have do not work well with 64-bit software, only the SATA 3 Solid State drives. I find it works better than 32-bit Software, therefore I installed and made it a 64-bit System to use, it works great.
HP mini 210-4000cto with Intel N2800 CPU and Intel Graphics Media Accelerator 3600 Series and Intel Chipset NM10.
The CPU can use 64bit - Intel wrote: Instruction Set 64-bit and Max Memory Size (dependent on memory type) 4 GB.
At Intel N2800 is found here: http://ark.intel.com/products/58917
At Intel NM10 is found here: Specifications or Chipset diagram
HP mini 210-2177nr uses N550 and NM10
AT Intel N550 is found here: http://ark.intel.com/products/50154/
At Intel N550 it wrote: Instruction Set 64-bit and Max Memory Size (dependent on memory type) 2GB.
Intel wrote this will use Intel Graphics Media Accelerator 3150
The RAM, I use, in HP mini 210-4000cto is made by Kingston - KTT1066D3/4G yet more companies can make a 4GB RAM for this Computer.
Both wrote: Instruction Set 64-bit, therefore both HP mini 210-2177nr and HP mini 210-4000cto have 64-bit. To use 64-bit it must be 32/ 64-bit BIOS yet for 64-bit it must be compatable software - it must be 64-bit, drivers, and Operating System, must of the drivers did come from HP for HP mini 210-2177nr.
HP mini 210-4000cto uses 32-bit/64-bit N2800 CPU and NM10 Chipset and Graphics GMA 3600. Graphics GMA 64-bit is hard to find, only 32-bit, yet I found I did find 64-bit, when I checked HP and Intel, I could not find it.
Now my problem is where to find 32-bit / 64-bit BIOS Software, for HP mini 210-4000cto there is only 32-bit BIOS Software for it, not 32-bit/64-bit BIOS Software. Where or when HP 32-bit/64-bit BIOS Software will be available is something I would like to find and use?
