That depends on what FS you use. But yes, Gentoo supports 137GB HDD's.

Yes, this is a Linux based system, and it supports harddisks larger than 137 gb.
I have a 640 gb reiserfs partition without any problems.

Does this require special hardware? My system has a UltraDMA/100 controller. Is that enough to support >137GB drives? |

Yes assuming your bios isn't crippled. If you have an older machine you may need to flash the bios to run larger hard drives. I know I had to for my older Compaq PIII Deskpro.

Why does the BIOS matter? Doesn't Linux take complete control of the hardware in this case? |

Many older BIOS assumed you'd never have a hard drive larger than X over the years. So when you installed your fancy new drive, the computer would only see Y part of it. Your OS would take the computer's word for how big the hard drive was and you'd be missing part of your space. This has happened a number of times over the years. The psuedo 137GB limit is just the latest interation. Here's a good link explaining it.

I'm well aware of the various drive size limits over the years, but this is a brand new drive. Will the Linux fdisk and mkfs commands let me use all 160GB of the drive, or will they only see 137GB?
I would assume that the Linux 2.6 IDE driver will ignore the size reported by the BIOS and determine the size itself. Is this an incorrect assumption?
Do I need to use the "hda=stroke" boot parameter? |

Brand new drive has nothing to do with it. Linux has some upper end limit of around 2TB depending on filesystem IIRC, but as I said this particular problem has never been filesystem or OS issue, except for the old 2GB limit.
kashani, running linux on a 1.9TB array and booting from a 250GB SATA drive.
