    2222The ATA stack in use by Haiku has known issues with some chipsets. If your system fails to boot with the "did not find any boot partitions" message, please try to disable DMA in the safemode settings of the bootloader. To enter the bootloader menu press space as soon as Haiku starts to load (before the splash screen appears). In any case, please report this issue to our bug tracker (see below).

    24 It is known that Haiku doesn't even begin to load on some media/BIOS combinations. The symptom for this specific problem would be that the system stalls or resets before the splash screen comes up. This has been observed when trying to boot from some USB sticks in combination with some BIOSes. It is possible that the very same USB stick works fine on other machines. The problem is not yet identified.

     26LiveCD and first boot performance: After an initial installation or a boot into LiveCD mode, some background tasks are executed to finish the installation setup. This is known to degrade performance. On harddisk installs this usually is not a problem as the tasks are done quickly. In LiveCD mode and also when booting from USB the performance hit more prominently visible due to the usually bad seek performance on CDs and the slow write back of small files on USB devices. Since the CD is read-only, this setup takes place on every start of the LiveCD. On writable media it will only be done once, so further boots shouldn't experience the same delays.

    2628The hda driver for HD Audio devices is known to fail with at least some VIA and nVidia devices. Some newer codecs are also not yet supported.
     
    3234DriveSetup does not install a basic bootloader when partitioning a disk. This requires bootman or another MBR bootloader to be manually installed on hard drives that were previously blank.

    34 It doesn't have an up-to-date web browser (Firefox/BonEcho 2.x).
     36Only some USB mass storage devices are not supported. There are different protocols for USB mass storage and currently only transparent SCSI is supported. Most of the current USB sticks make use of this protocol and should work. Some, mostly older, USB sticks and some USB CD-ROM drives do use different protocols however, so they may fail to boot Haiku or may not be recognized if plugged in.

     38Haiku doesn't come with an up-to-date web browser (Firefox/BonEcho 2.x).

    3640USB Keyboards attached to OHCI or to USB 2.0 hubs do not work in Kernel Debugging Land (KDL). They need to be connected to UHCI root ports to work in KDL. Also note that when entering the kernel debugger by means of a panic it is possible that the keyboard does not work. To work around this issue you can manually enter the kernel debugger once and leave it again to enable the USB keyboard.
