Inferno - Errors in the previous numbers.

            Some errors


                ZX-Guide # 2


   In describing the interface Beta Disk non
correctly specified level, opting density
record. It should be D6 (as shown in
Larchenko and Rodionov), but the MFM = 0, FM = 1 (a
not as stated in Larchenko and Rodionov).
Procedures for TR-DOS installed D5, but not
understand why.


                   IG # 6


   In sketch No. 5 used construction
function INC H, L. Because of this, we obtain If
SHKOM short period of sequence
random numbers - just 256. To write
INC H, HL. Just INC HL is not recommended,
as in ROM is a great sequence
identical or similar bytes.


                   IG # 7


   If you get a version of IG # 7, which is not
Georgia's "errata", then rename
disk file errata!!. W in Errata!!. W. He
prevented because the engine of the journal is looking for a 
hundred Chi on the first 4 characters name, and not only

in the archive, but also outside. A file was added
in a hurry after the assembly of the magazine.

           IG # 7 - "Turbo Sound"


   Capacitors C1, C2 can not be 0.1mkF
- You should at least 10mkF.

   In the case of PUSH HL: SBC HL, DE: POP HL has

             IG # 7 - "DNAmake"


   Indicated that the element FINDER, if not
was an element that he is looking for returns
error 0.0 (which is the message "all OK"!). On
Actually, it returns an error 0,1 (PIC
motrel in source: 0 - number of the element, 1
- The number of errors).

  IG # 7 - "The location of partitions on the HDD"


   It turns out that for all sectors in the FAT32
cylinder 0, except for the very first - free
Ny, and references therein Sector 2 (counting from
units) and sector 6 (counting from one) -
this sector from the beginning of the section, and they are 
there exist within each section.


   At sector 6 holds a copy of boot-sector
pa (ie the very first sector of the times
case). And the article pointed out that in sector 6
- A copy of the partition table.

   I finally found out where the older stores
two-byte numbers cluster in FAT32 (ibid.
4 bytes): it turns out, the spare area
out of ten bytes at offset 20, 21 by at
We first directory entry.

              IG # 7 - "Video"


   Was omitted instruction: what to do
when AVIStreamOpenFromFile (...)!= 0. Prog
Ramm should look like this:

bool vzx_avi_open (LPCSTR szFile)
{
vzx_hdd = DrawDibOpen ();
AVIFileInit ();

 if (AVIStreamOpenFromFile ('vzx_avi, szFile,
 streamtypeVIDEO, 0, OF_READ, NULL)! = 0)
 {

   MessageBox (HWND_DESKTOP,

    "Failed To Open The AVI Stream",

    "Error", MB_OK);

  return vzx_ok = false;
}

...

}
