comment Hard Drives and types — What makes them so different?
@CanadianLuke, that bit about parking made no sense. Parking itself is a seek operation so it isn't something that can be done during a seek operation. Also it is the green drives, not black, that park their heads after 8 seconds of inactivity.

comment How BIOS extensions (option ROMs) work?
@RJSmith92, like I said, it is only used to switch modes, so the rest of the time it can be disabled. It also may be copied to ram and run from there. Come to think of it, most bioses back in the day had options to shadow the bios and video bios in ram. After copying it to ram, it would be disabled.

@RJSmith92, yes, if you use the base vga driver then it should remain enabled, but it is only used for setting the resolution, not drawing to the screen.

@RJSmith92, windows disables the mapping because it doesn't need it.

comment Is it possible to FAX over broadband?
What in the world do you mean by "broadband"? You mean you are tethering to your cell phone?

comment 7z a folder in chunks of 100MB and decompress
You have to be more specific that "doesn't work"

@RJSmith92, because Windows doesn't run in 16 bit mode, it has no need of the bios oprom, so it unassigns it.

comment How can i manage10 SATA drives separately with same speed as DAS
@user1721949, put the name in the search box at newegg.com or something and you will find a bunch. They come in all sorts of different shapes and sizes, but the principal is simply that it's a box that holds drives, has a power supply and fan, and one or more SAS or SATA connectors.

comment How BIOS extensions (option ROMs) work?
@RJSmith92, pretty much, yea. VGA bios hooks int 10h, which provides an api for basic text output, and disk controllers hook int 13h, which provides basic disk read/write interfaces. You might google for Ralph Brown's interrupt list for the nitty gritty details.

comment GZIP corruption with big files?
Did you leave out the cd folder, or folder/ prefix to the second gunzip, or do you have a different b.qow file in the current directory?

comment How BIOS extensions (option ROMs) work?
@RJSmith92, yes, generally devices only request addresses in the old 0xC0000 to 0xF0000 range for bios oproms, and use addresses in the 3-4 GB range for MMIO.

comment New ram prevents PC from booting up
@Ramhound, sure it does; touching the chassis ensures that there is no voltage between you and it. Unless you are rubbing the chips on the ground, then it doesn't matter if there is any potential between the chassis and ground.

comment How can my program make IPv6 connections?
Well obviously you are either mistaken about it making IP6 connections outside your local network, or the router does support it.

comment CPU power states and temperature spikes
If you mean on average, then yes since there is always some activity waking up the cpu, but during the time when it is actually idle, if it is functioning properly, it is totally powered off and thus generating no heat. While it isn't going to get down to 25C, it should be well below 80. Come to think of it, my cpu ( sandybridge quad core 3.4 Ghz ( 4.3 turbo ) 2500K unlocked and slightly overclocked ) does idle at around 30-32 C, which is getting pretty close to 25.

comment CPU power states and temperature spikes
95 may be normal under full load with performance boost, but certainly not when idle. Either you aren't really idle or your idle is broken and not making use of the processor's C states.

comment CPU power states and temperature spikes
If the cpu is idle though, it's performance state should not matter; it is powered down and not generating any heat.

comment How does fabrication process and compiler quality affect CPU performance
Fabrication means manufacturing the cpu ( silicon ), not software.

comment Difference between cache memory and register?
As the accepted answer from 4 years ago says: cache just sits between the cpu and main ram, which is where instructions and data are stored.

comment How to convert RJ11 to RCA
@BGM, that looks like what you need. A telephone line is only two wires. An RJ11 contains two lines: one on the inner pair of pins, and line two is the outer pair of pins. As for low power, "low" is relative. RCA is something like 3v and telephone voice is like 12v, and that 48v ringing voltage is what would really kill it.
