I have another bug fix for hard disks. I own a Micro-1 turbo XT with a unknown
made-in-the-orient controller and a 20mb hard disk. I was getting so many disk
errors before this fix that I could hardly do a mkfs without getting into
serious trouble. The same symptoms showed up on all the Wyse PCs at my office
which uses a Adaptec controller. The problem was fixed in the routine com_out
in the file xt_wini.c by holding the interrupts turned off untill after the
status port has been read, right after the 6 command bytes are output to the
controller. This fixed all the problems for my Micro-1 as well as the Wyses at
work. Might want to give this a try if you have hd problems. I posted this
article sometime ago, but because of our news engine having difficulties, I
doubt it made it out of our site.
