[comp.sys.ibm.pc] Turbo v Hard disk- Help!

c60a-2dk@e260-2a.berkeley.edu (Jeff Yu) (11/27/89)

Help!  I recently installed a Seagate hard drive (ST-277R) into an XT clone
running at 4.77 and 8 MHz using a Western Digital Controller
(WD1002A-027X).  This setup works fine, as long as I leave the turbo off.
When the machine is running at 8 MHz, reads and writes to the hard drive are
unreliable.  Has anyone encountered this problem before?  If I turn the
turbo on after the file has been loaded, there is no problem, so there is
nothing wrong generally with the turbo.  Could the cause be in the BIOS?  If
so, is it possible to swap only the BIOS on a motherboard?
