[comp.sys.ibm.pc] Unable to install Dos 3.3

MGREENE@AUVM.BITNET (Michael A. Greene) (10/29/89)

Just failed in replacing DOS 3.1 with DOS 3.3.  Machine is an IBM PC-Portable
witha Seagate 238, an 8087 and a V20 instead of the 8088.

I followed the procedure in the friendly manual as follows:
   a.  Booted from drive A.  This put me in Dos 3.3.
   b.  SYS'ed the hidden files onto C.  Got "systems transferred msg"
   c.  Copied Command.Com and everything else in with REPLACE.
Then I tried to reboot.  No msg on the screen, just a blank screen.

After this I thought maybe it was something in the autoexec or config.sys
file.  I renamed them to something innocuous and then tried to reboot again.
Still no luck.

Help.  Please send results directly.  I will post if anything interesting
emerges.
