SU: Release Notes 1571 ROM upgrade
FM: D. Siracusa
DT: 05/20/86
Rev. to ROM 310654-03
I would appreciate any comments to the bugs or anomolies
listed below before I make release for the 1571.
1. Previously during a BURST GCR FORMAT the activity led was
not activated. This has been remedied (1571).
2. A bug in routine 'STLBUF' prevented buffer allocation and
caused the SAVE@ bug. This has been remedied (1541/1571).
3. The 1571 Burst Load Utility would not load 'Locked Files'.
This has been remedied (1571).
4. A bug in routine 'TSTATN' caused device not present errors,
the irq source was never cleared in the 6522. This has been
remedied (1541/1571).
5. Previously an active collect in 1541 emulation mode would
write a zero to the double sided flag in the BAM. This has
been remedied (1541/1571).
6. Previously BAM allocation on side one would write the BAM
image to the diskette every access. This has been remedied
(1571).
7. In Routine 'SPINP' interrupts from SP (fast serial input)
were not enabled properly, this has been remedied but has no
affect on the operation of the serial bus (1571).
8. Previously if a copy was performed addressing drive one, the
error channel would return status 00, OK,00,00. This has
been remedied (1541/1571).
9. Motor acceleration time for the MFM controller was too long
and affected performance when reading and writing in MFM
format. This has been remedied (1571).
10. Previously determining whether a diskette was GCR
double-sided or single-sided would take too long due to
valid sync pulses found on 'flippy diskettes' and MFM
diskettes. This has been remedied (1571).
11. Previously the rom test did not check the first page in ROM
memory. This has been remedied (1571).
12. Previously while loading files using the Burst Load Utility
retries were not performed properly. This has been remedied
(1571).
13. Due to a bug in routine 'USEDTS' a block not available
status was returned when blocks free were equal to 3. This
has been remedied (1541/1571).
14. With multiple files open and sectors being allococated on
both sides the BAM swapper mechanism would trash BAM side
one. This has been remedied (1571).
NOTE: Below (1541/1571) implies that the bug occured in the
1541 as well as the 1571 disk drive. While (1571) implies
that the bug only occured in the 1571 disk drive.

Dave Siracusa Commodore Technology, West Chester, PA William K. Sims University of N.C. Chapel Hill, N.C. 27514 Dave, Your artical ref the Rev. to ROM 310654-03, was most interesting. I woul like to response to some of the items you have called out. First, however, my equipment here, is a C128 (2) 1571's (1) 1541. I am using the C128 for this function now (Unix). ITEM REMARKS -------------------------------------------------------------------- 1 I have this happen in the C/PM mode. 2 I have not noticed the problem. 3 I have tried to load locked files with no success. 4 /TSTATN/ device not present has happen lots of the time, both in the 128 mode and in the C/PM mode. (I am using two 1571 drives). 5 I have not noticed this problem. 6 I have expperienced this, when formating a disk for double sided. 7 I have not noticed this problem. 8 I have not notice this problem since I am not using dual disk drives. 9 I have not noticed this problem. 10 I have noticed this, but has not been a problem for me. 11 I have not noticed this problem. 12 I have not noticed this problem. 13 I have not noticed this problem. 14 I have experienced this, however this has not showned to be a problem with me. I hope this will help you in some of the bugs and anomolies in the 1571. Now that you are about to remedie these problems, what will I have to do to get the ROM chips. Would it be possible to get the necessary CHIPS to remedie my problems. I would be happy to make a report back to you as to the effect it has with my setup. Best Regards, Bill Sims (ubsims@ecsvax)
