Just a warning for any Fedora Linux users preparing to upgrade to Fedora 7: Grab the Live CD first and make sure that all your hardware works properly. If not, see if the fix is available before you actually upgrade.
I upgraded a system with a Permedia 2 video card, which uses the glint drivers. The installer couldn’t launch the GUI, but I’ve run into that fairly often, so I just used the text-based installer without thinking much of it. The upgrade process itself went fine, but on booting into the new system, it was unable to launch X. I kept getting the following error: Continue reading
If you want to build a Linux or FreeBSD system around a RAID array, don’t use the Promise SuperTrak SX6000 controller. At least not for now.
The card used to work under Linux using the standard I2O drivers (i2o_block, etc.), but sometime last year Promise changed the firmware so that it no longer uses I2O. Now you’re stuck with Promise’s own driver, so if you want to use an old enough distribution* (say, Red Hat 7.3) that you can find a driver disk, or make your own driver disk, go ahead…but don’t expect to be able to upgrade it unless you can create a driver disk for the newer distro. This assumes the source code for the driver will work with recent 2.4 kernels—it won’t compile with 2.6. There has been talk of merging the pti_st driver into the kernel (fortunately it’s GPLed), but I can’t find anything more recent than August. Someday it might work again, but not today.
Now, FreeBSD is another matter. It has built-in drivers (pst), the installer will detect it automatically, and even let you install your entire system to it—without warning you that FreeBSD can’t boot from the SX6000. You can boot from another drive and interact with it once the system’s running, but you can’t put your entire system on the RAID array. (This information is not in the installer, not in the hardware notes, not in the driver man page. I only found the one 1½-year-old mailing list post by the driver’s author, and a bunch of “I don’t think it works” comments in other lists and forums.)
I hope this post will save someone a lot of frustration.
*Of the distributions for which Promise has provided driver disks, only one—SuSE 9.0—hasn’t already been retired.
One of the reasons our Powerbook stays in Mac OS most of the time (aside from the fact that It Just Works™) is that Yellow Dog Linux 3.0 didn’t have drivers for Airport Extreme, so it can’t connect to the wireless network. I had hoped that YDL 4 (just released) would resolve this — perhaps the driver was only available for the 2.6 kernel, or something.
I finally started looking, and that’s not the case. It seems that the Airport Extreme chipset manufacturer, Broadcom, refuses to release Linux drivers or to release specs to allow anyone else to write Linux drivers.
I don’t expect it to do any good, but I signed my first online petition.
Ah, well, I can do almost everything under Mac OS, and for those occasions that I actually need Linux, I can always go solo or plug in a cable, though it does limit where I can hook it up.
