Generally you type int he sequence where you run
what's in memory at the
beginning of the ROM address, usually C800 as the primary controller. At
the
Debug prompt you type G=C800:5 or it may be G=CC00:5
or G=D000:5 as well
as
another I forget. It also is dependant upon the
controller itself but
they
usually followed some standards.
I'll need to try the other addersses. I'm basically assuming that
<G=C800:5> is an incorrect address, since it causes the computer to reboot.
Once the program starts you have to figure out what
they're asking for as
this
is where they get different. Western Digital
controllers were pretty
striaghtforward.
That they were. I've worked with them in my Tandy 1000's.

Ding ding ding!!!
Hold on!
I got the info off the HD bible and I found what we need to know:
Most WD, SMS/OMTI use C800:5
few did use C800:6
But the Adaptec 8 bit card use weirdest way to do LLF process:
C800:CCC
and you have to input the needed info in hex.
Honestly, I prefer WD 1:2 or 1:3 controllers, the good ones are
XT-GEN kind.

PS: How did I know something is still wrong because I was been there
before. Oh, those 8 bit adaptec MFM cards have highest failure rate!

Now that you mention it, I know the CCC is correct but it slipped from not using an
Adaptec
controller since the big heydays when everyone wanted to format ST-225's with an
Adaptec RLL
controller (and a couple other high end controllers) to make the 225 into a 30mb drive
instead of
the MFM 20 it was made as.

Instead of using the G= routine, first locate the card BIOS using the D
function. You will almost invariably find ASCII text that will identify
code found as the card's. Check C800:0, CA00:0, and so on in 200:0 steps
on through Dn00:0. When you find some likely code use the L function to
see if there is a JMP around xx00:5. If so, then try the G= bit. Saves
a lot of rebooting! Remember, not all HDC BIOSes have such a jump start.
