>From: bde@kralizec.zeta.org.au (Bruce Evans) Subject: cache botch in bootstrap Date: Sun, 20 Feb 94 18:14:35 +1100 The cache in the bootstrap loader didn't allow for the device changing. This caused surprisingly little trouble - the cache is only for a single track (or part of a track), and the first access to a new device is always for an early sector, so there is no problem unless the last access to the old device was for an early sector. I saw the problem on a system with BSD on wd1 and no label on wd0. Everything worked if the the device name wd(1,a) was specified before the default of wd(0,a) was tried, but when the default was tried, it failed on the first sector because there was no label, and then the first sector on wd0 was always used instead of the first sector on wd1, so there was apparently no label on wd1 either.
