Hello All, I'm trying to compile and run SIMH on CentOS 5.6. I've followed the instructions at http://www.wherry.com/gadgets/retrocomputing/vax-simh.html but when I try to boot from the CD image, I get: [root at zork data]# /usr/local/vax/bin/vax VAX simulator V3.8-1 NVR: buffering file in memory RQ: unit is read only Eth: opened eth0 KA655-B V5.3, VMB 2.7 Performing normal system tests. 40..39..38..37..36..35..34..33..32..31..30..29..28..27..26..25.. 24..23..22..21..20..19..18..17..16..15..14..13..12..11..10..09.. 08..07..06..05..04..03..

The CD image file I made directly from the Montagar 7.3 CD. The vax.ini file is exactly as shown on the instructions page. Thanks in advance for any suggestions! Ian
