im not sure if this has been fixed in the new version of the updater but in ver 506 i had a few errors. the problem lies on line 1144 slipstream_DPM.cmd 1143: %T1% d1,hpt366.sys 1144: %T1% d1,hptmv6 1145: REM IBM 1144 should read %T1% d1,hptmv6.sys if im not mistaken The same error is on 1252 Also RHPT3XX.SYS is missing from DOSNET.inf if it has been fixed then ignore this post. im not on the net all day so i cant check if this has been resolved. but if not i hope this solves some probs in future releases
