It was my understanding that although the hardware is the same, the ROM firmware would have to be different. Or it was just the real InfoServer which had a crippled firmware just NOT to allow booting VMS on it? The needed software is available on OpenVMS Freeware 8, disc 1. There's a Zip file where the needed images are. You just have to burn two CD's, the Infoserver software CD and the Disc Function CD. Kari, do you know the meaning and use of the various files inside the software CD? In the [SYSD] root there are SYSBOOT.EXE, SYSLOCS.EXE, and LOCSUPDATE.EXE which is functionally equal to the IS1000_V35.SYS file present in [SYS0]. Moreover, in the [SYSD] root there is also a ESS$BOOT.PAR file which is an ODS-2 image containing again SYSBOOT.EXE and SYSLOCS.EXE (exactly equal to the former) and LOCSUPDATE.SYS which is identical to IS1000_V35.SYS in [SYS0]... Chineese boxes indeed! When you have the HW assembled and burnt the CD's you just boot from the Infoserver software CD like: B/R5:D0000000 <cd drive> Then the MicroVAX will boot the Infoserver software from the CD and then you will be able to install the software on the disc drive. Something like: InfoServer> SET SERVER STATE OFF InfoServer> INITIALIZE DK1 InfoServer> UPDATE SYSTEM DK2 DK1 InfoServer> SET SERVER STATE ON DK2 Should be the first CD-ROM and DK1 should be the system disk. See the following "InfoServer System Operations Guide" (file name mismatches): http://h30266.www3.hp.com/masterindex/installation_guide/installation_guide… Then you can create a partition on the disc sufficiently big to have space for the OpenVMS VAX CD contents. Do remember to enable MOP. When Wouldn't it be enough to directly serve the VAX OpenVMS CD-ROM off the InfoServer without copying its entire contents into an Infoserver partition? The InfoServer would use the ISL_SCRIPT.ESS file found in [000000] to automatically MOP-serve the ISL files. Cheers, G.
