VENEER.EXE is a Microsoft COFF executable used to start the boot sequence for Windows NT on PowerPC.

Description

VENEER.EXE is an ARC firmware implementation that runs on an existing Open Firmware environment.[1]

Notes

  • It treats IDE devices as SCSI devices.[2]
  • It only recognizes 601, 603, 603e, 604, and 604e CPUs.[3]
  • It appears to be present in the Windows NT source tree. Version 3.0 has strings referring to files in D:\nt\private\ntos\boot\veneer\, and Version 3.03 has S:\BUILDS\NT400\1345.960918\SRC\DAYTONA\MOT\VENEER\.
  • Version 1.0 complains about multi, whereas Version 3.0 and 3.03 do not. Version 1.0 will print: GetDeviceAttribute: node multi(1) not PeripheralClass.
