AX5/PX5/TX5Features
TheAX5/PX5/TX5havebeenespeciallydesignedforFileserver,
WorkstationandProfessionalusers.Itcansupportawiderangeof
processors,includingall IntelCPUs(P54C)andIntelCPUswithMMX(P55C),
aswell asall AMD-K5/K6andCyrix6x86/6x86L/6x86MXCPUs.Italsotakes
intoaccount,asmuchaspossible,all futureCPUs.
TheAX5/PX5/TX5usesSOFTMENU™technology,whichmeansthat
all theparameterscanbeconfiguredwithoutusingDIPswitchesorjumpers.
Theconfigurationisentirelyachievedthrougha“SoftSwitch”thatallowsthe
