Was this a limit that existed in earlier VAXstations? VMS, generally, doesn't have any issues unless you're booting the system with older built-in controllers. Even then, if you can organize the VMS files needed for bootstrap, you can probably boot from a larger system drive too. -- VAXman- A Bored Certified VMS Kernel Mode Hacker VAXman(at)TMESIS(dot)ORG Well I speak to machines with the voice of humanity.

The good news is that there is a famous patch for those ROMs. Here it is: http://ftp.gwdg.de/pub/vms/ka420/ He is the guy who also patched VAXstation/MicroVAX 2000 ROM and VAX PKDRIVER in order to use the internal SCSI "tape controller" for disks too: http://ftp.gwdg.de/pub/vms/pk2k/ HTH, :) G.

AFAIK it's not a myth for the microVAX 3100 series, except the models 8x and 9x. The same for the VAXstations 3100. The VAX 4x00 models and the VS4000s have no limit, at least not today. The limit is a little over 1.0 GB btw. Large capacity SCSI drives usually have SCA interfaces. So a converter is required to match the 50 pin connectors in a VAX. Not all converters work and the faulty ones fed the myth, I think.

There we go - found it: http://labs.hoffmanlabs.com/node/541 But it's on the 3100. The 4000 seems to be okay.

There also seems to be no 1G boot drive limit on this as my boot drive is about 4G. Was this a limit that existed in earlier VAXstations? The ROM code in the VAXstation-3100s used only 32 bits for the SCSI LBA, so that limited them to booting from disks less than 2Gb. Later models (like the 4000 you mentioned) fixed this, and there was never a limit. Actually even the 2GB limit on the 3100 could sometimes be ignored. It would still work with bigger disks so long as all the files the ROM needed to access for booting were in the first 2GB (i.e. the upper bits of the LBA were zeros). If you'd just installed VMS on an empty disk, this was usually the case. And this was only a problem with the ROM in the 3100. Once you got VMS booted the SCSI device driver had no issues with the disk size. Bob

Need a non-static-IP link to HECNet. Anyone got one available.

Guys, sorry about not having the VPN accounts up yet, my Internet connection SUCKS right now, anything interactive like an SSH session to the server is like pulling teeth.

Compiler issues continue

by hvlems＠zonnet.nl

If the c compiler is distributed as a set of save sets, .A .B etc then do a back/ list on them to find the .cld file. Use the set command command to install the cc command. That may work for you perhaps.
