    2424It 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 or CD works fine on other machines. The problem is not yet identified.

    26 LiveCD 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.
