FreeBSD currently runs on a wide variety of ISA, VLB, EISA and PCI bus based PC's, ranging from 386sx to Pentium class machines (though the 386sx is not recommended). Support for generic IDE or ESDI drive configurations, various SCSI controller, network and serial cards is also provided.
A minimum of four megabytes of RAM is required to run FreeBSD. To run the X Window System, eight megabytes of RAM is the recommended minimum.
Following is a list of all disk controllers and Ethernet cards currently known to work with FreeBSD. Other configurations may very well work, and we have simply not received any indication of this.
