Don't understand well what I have to do with this program: it can help me to format the drive or you have to patch and send me a new rom for let the drive be compatibile with the Winny?
Version 2.07 is a LRESPR version which will override ROM copy (which gets copied to ram on initialisation). The idea was to use it to experiment with, in an attempt to get your unknown drive working. The Basic program just let you know what the ISA card/drive identity is set to.

Then you need find out what your drive parameters are sectors/heads/cylinders etc.

The drive parameter table in version 2.07 can then be patched liked this:

Code: Select all

100 addr=ALCHP(40) : LBYTES flp1_mhd_bin,addr : CALL addr
110 id=PEEK_W(addr+38) : RECHP addr
120 ch%=FOPEN('flp1_v2_07S.bin')
130 WPUT#ch%\3562;id
140 INPUT 'interleave ='!d
150 WPUT#ch%\3570,d
160 INPUT 'sectors per logical block ='!d
170 WPUT#ch%\3578,d
180 INPUT 'sectors per cylinder ='!d
190 WPUT#ch%\3586,d
200 INPUT 'heads ='!d
210 WPUT#ch%\3594,d
220 INPUT 'cylinders ='!d
230 WPUT#ch%\3602,d
240 INPUT 'maximum cylinders ='!d
250 WPUT#ch%\3610,d
260 INPUT 'cylinder for write precomp ='!d
270 WPUT#ch%\3618,d
280 INPUT 'cylinder for reduced write current ='!d
290 WPUT#ch%\3626,d
300 CLOSE#ch%


All sent to a friend for check it ;)

It will read the post this night, hope It can make it works.

Thanks a lot!

It start, format but no way to initalize it on the Winny.

The drive seems works but It need to be correctly partitioned but how?

I've sent all to my friend Paolo, hope that can test this program too.

THanks.

Hi all, unfortunately all my tricks to recover the old hd is going bad; I've also replaced the rom with the last version and nothing happens so I suppose that all hd's are fault.
In effect we are speaking about some pieces of hardware of about 30 years old!!
I'm very sorry but I think that we need to find a mfm/rll hdd that is tested to be sure that the miracle hdd system is ok

Hi,

Reading the message thread again, it looks like the hard drive is not paired with the Hard Drive Interface.

The way to perform this pairing of Hard drive and interface is to install the Hard Drive into a PC with ISA Bus, set the CMOS Hard Drive setting to 0, which is not installed.

Boot the PC into MSDOS and use DEBUG to pair and partition the drive.

See Page 12 of the attached manual for Seagate ST412 Interface Controller-ST11M-ST11R

Then use the QL to format drive.

If you are still having problems, then send to me and when I have time I will do the required work.
