This currently has to be done in the source code and re-compile Clover. Clover does this if you set QPI to a string value of 0.Ģ - Set SMBIOS table type 4->ExternalClock to 0 (or 25Mhz as a real Mac). To achieve that with Clover here’s what to do:ġ - Drop SMBIOS table type 132 for Sandy Bridge and newer CPU’s. Note: Real Mac’s report a hw.busfrequency = 100000000 Apparently this value only makes sense for Nehalems, the rest should use the formula stated above - or nothing at all. After a long argument this value was sourced into the configuration file - write what you want (in MHz). AppleSmbios sources describe two variants: either SMBIOS already contains this value as specified by the vendor, or it is calculated by the formulae BusSpeed*4. Clover has a corrected algorithm according to Intel data sheets. Chameleon has an algorithm for calculating this value for Nehalem CPUs (, which is however not correct). System Profiler calls it Processor Bus Speed or Bus Speed.
It is recommended manually specify the value, which is calculated more accurately during a boot with Clover EFI. If ASUS uses a rail frequency of 1600 MHz and a multiplier of 8, the formula does not work - a CPU with 12,8 GHz does not exist a division into 4 is required.Īttention: UEFI booting will produce an inaccurate value. You can distinguish them according to the scale: either it is from 100 MHz to 400 MHz or it matches the formula CPUFrequency=RailFrequency*CPUMultiplier. Some vendors use a different meaning for BusSpeed and FSBSpeed and use values four times bigger in the BIOS. For example my DMI has a value of 100 MHz, however manually overriding it to a value of 99790 kHz produced better clocks. You can choose a more accurate value, if needed. If it is slightly incorrect, clock issues may arise and the system will behave in a strange way.Īn automatic detection was introduced with revision 1060, which relies on the ACPI timer producing much more accurate values than the ones stored in DMI.ĭMI stores this value in MHz, which is not accurate in contrast to a value calculated from CPU frequency. If this value is not correct, the kernel will not start at all. It is passed from the boot loader to the kernel. Very important value for a stable system.

Even though, most trial software products are only time-limited some also have feature limitations. After that trial period (usually 15 to 90 days) the user can decide whether to buy the software or not. Trial software allows the user to evaluate the software for a limited amount of time. Demos are usually not time-limited (like Trial software) but the functionality is limited.

In some cases, all the functionality is disabled until the license is purchased. Demoĭemo programs have a limited functionality for free, but charge for an advanced set of features or for the removal of advertisements from the program's interfaces. In some cases, ads may be show to the users. Basically, a product is offered Free to Play (Freemium) and the user can decide if he wants to pay the money (Premium) for additional features, services, virtual or physical goods that expand the functionality of the game. This license is commonly used for video games and it allows users to download and play the game for free. There are many different open source licenses but they all must comply with the Open Source Definition - in brief: the software can be freely used, modified and shared. Programs released under this license can be used at no cost for both personal and commercial purposes. Open Source software is software with source code that anyone can inspect, modify or enhance. Freeware products can be used free of charge for both personal and professional (commercial use). Freeware programs can be downloaded used free of charge and without any time limitations.
