Mac: use a Windows ATi Radeon 4870 in your Mac Pro

Monday, March 16th, 2009

The price for Windows 4870 cards is substantially lower than Apple’s.
The Canada Apple Store currently
lists one for $420,
whereas
Canada Computers has one for $210.
In
this MacRumors forum thread
people are discussing how to do this and what the pitfalls are.

Basically, download and flash the ROM from
RapidShare.

One person said:

I just tried it on my Sapphire HD4870 (the 1st gen one, based on
ATI’s ref design).

I flashed using freedos and the following command line:
atiflash.exe -p -fs -fp 0 4870.rom
note: -fs and -fp are used to ignore SSID and P/N mismatches

And it works!

EFI driver is initialized correctly, (I don’t have the leaked MacOSX
drivers for this card, so I can’t tell if this one works too), and
bootcamp stil works (currently writing from GNU/Linux on my 2006 Mac
Pro).

Only problem is : only one output is active, no dual-head, it seems
(at least using ATI’s linux driver)

I should note that doing this seems to make the analog output (SVGA) not work. DVI is fine, though one person reported the “top” port as only going up to 1024×768.

Be careful out there. Read the thread for info on which cards work, and what possible side effects there are.

YMMV.

hard drive prices

Friday, March 13th, 2009

Bought a new hard drive today; a 1½ terabyte drive for $160.
Thats only 10?¢ per gigabyte!

Scott showed me
a site
that says the first hard drive was $10,000 per megabyte!
So over 50 years, the price of hard drive storage has dropped by a factor of a BILLION.

At this rate, by the year 2059, the lowest cost of storage should drop from the current cost of $100,000,000 per exabyte to 10¢.

podcast

Thursday, March 12th, 2009

I’d like to record a podcast with one or more other interested individuals, using some sort of software that allows both a multi-party voice chat, *and* records each person’s audio locally in a high-qality format suitable for remixing in post.

I think I remember such software being mentioned somewhere, but I’m not sure where.

Any volunteers? … Bueller?

Mac OS X command-line of the day

Friday, March 6th, 2009

sudo xattr -d com.apple.quarantine *

This removes the “This file was downloaded, are you sure…” warning when dealing with downloaded files.

There are attributes other than com.apple.quarantine, such as:

  • com.apple.ResourceFork
  • com.apple.FinderInfo
  • com.apple.diskimages.recentcksum
  • com.apple.metadata:kMDItemWhereFroms
  • com.macromates.caret

I like that last one.
I guess it’s how TextMate
remembers its position in a text file.

If you want to see what extended attributes your files have, you can either use “xattr -l filename” or just “ls -l@“.
