Aucbvax.4187 net.2bsd-bugs utzoo!decvax!ucbvax!pur-ee!purdue!jrs Sat Oct 3 03:14:07 1981 While installing the 2.8BSD software, I encountered the following problems. The fixes listed below appear to work on our system. 1) ~/standalone/bootstrap/M.s I could not get a kernel with an instruction space bigger than 56K in size to load, even though we are running on a 11/70 which has split I/D. It appears that the last kernel I space mapping register was getting set to point to the I/O page regardless of the fact the we were running split I/D. 185a186,191 > cmp _cputype,$40. / Do not check for split i/d on 40s > beq 1f > bit $4,SSR3 / fix so that we can load kernel ispace >56k > / on split i/d machines > bne 2f > 1: 186a193 > 2: 2) ~/src/dev/xp.c I had problems getting reports of disk errors printed on the system console when we had a bad spot on a disk pack that we were using. It appears that the recalibrate function that is issued clears positioning in progress significantly long before it actually returns the drive to a device ready state. We are using the Emulex SC70 controller on a CDC9766 drive. Unfortunately, we do not have any DEC disk drives left so I do not know if the problem extends to these devices also. 512c512 xpds & PIP) --- > while((XPADDR->xpds & (PIP | DRY)) != DRY) - Jeffrey R.
