Installation of Windows 95 on DiskOnChip 2000

How to install NT on a large hard-drive [greater than 7.8 GB]?


Installation of Windows 95 on DiskOnChip 2000

DiskOnChip is flash memory device that makes full hard disk emulation through INT 13h.  Therefore DiskOnChip can work under windows 95 and it is possible to load windows 95 from big enough DiskOnChip.  But DiskOnChip is a memory mapped device, so installation of Windows 95 demands several special steps to avoid some unpleasant occurence of disk failures under Windows 95.  Especially it is important for Mutil DiskOnChips that uses more than one Window in upper memory for every single DiskOnChip.   Futher, the term DiskOnChip is also used for Mutil DiskOnChip.

Quick Installation Guide

1. Plug the DiskOnChip 2000 device into the 32-pin socket. Verify the direction is correction (Pin 1 of the DOC 2000 is aligned with pin 1 of the socket).

2. During power up you may observe the messages displayed by the DOC 2000 when its drivers are automatically loaded into system's memory.

3. At this stage the DOC 2000 can be accessed as any dick in the system.

4. If the DOC 2000 is the only disk in the system, it will appear as the first disk (drive C: in DOS).

5. If there are more disks besides the DOC 2000, the DOC 2000 will appear by default as the last drive, unless it was programmed as frist drive.

6. If you want the DOC 2000 to be bootable.  Please copy the operating system files into the DOC by using the standard DOC commmand (for example: sys d:)

7. If you want the DOC 2000 to be the first drive always, you should contact us to get DUPDATE utility.

Installation from Floppy:

1. Make the DiskOnChip bootable in DOS (ver 6.22 or 7 - windows 95)
1.1 Prepare DiskOnChip for work.
1.1.1 Single DiskOnChip is already ready.
1.1.2 To prepare multi DiskOnChip please read appropriate App. Note.
1.2  Boot from floppy DOS 6.22 or 7 (windows 95)
1.3  Format DiskOnChip in DOS and make it bootable: format c:/s
1.4  Reboot from DiskOnChip

2.  Install Windows 95 for first time.
2.1  Run Windows95 setup from floppies
      NOTE: This will be an old version of Win95, i.e. it will be 4.00.950
      This is before 4.00.95.a or 4.00.95b
2.2  Select compact installation
2.3  When you get to the final screen where it asks you to continue and reboot the system go ahead BUT make sure you reboot from a floppy.  It first checks that there are no floppies so you will have to let it finish and start the reboot process without the floppy and then hit the reset button.  It is very important NOT to let the DiskOnChip boot at this point - if it starts to boot from the DiskOnChip it might aleady be too late.
2.4  Boot from the floppy and edit the following file:
      C:\WINDOWS\SYSTEM.INI
      under the [386enh] section insert the following:
      emmexclude=d000-dfff         - exclude DiskOnChip memory range
      (this is just like what we used to do for Win3.x)
2.5  Reboot from the DiskOnChip and let Win95 finish its installation

3. Installation from CD-ROM

3.1  Do step1.

3.2 Copy from floppy to DiskOnChip appropriate drivers for CD-Drive and put appropriate lines to CONFIG.SYS and AUTOEXEC.BAT on DiskOnChip

3.3  Do step 2.

4.  Another way to prohibit from Windows 95 to access upper memory of DiskOnChip.

4.1 Put into config.sys on DiskOnChip during step 1:
     DEVICE = c:\DOS\HIMEM.SYS
     DEVICE = c:\DOS\EMM386.EXE NOEMS X=D000-DFFF

4.2  Windows 95 during step 2 itself will change these lines to
     DEVICE = C:\WINDOWS\HIMEM.SYS
     DEVICE = C:\WINDOWS\EMM386.EXE NOEMS X=D000-DFFF

 

 

How to install NT on a large hard-drive [greater than 7.8 GB]?

NT only, NO sharing of the hard drive with Windows 95/98

The motherboard BIOS must support and recognize drives larger than 8 GB
before NT can access the entire drive.

The system partition (boot partition) is still limited to 7.8 GB whether an updated
version of the ATAPI.SYS file is installed or not.
The CD is Service Pack 1.

1.Download ATAPI.SYS from Microsoft.
    FTP.MICROSOFT.COM/BUSSYS/WINNT/WINNT-UNSUP-ED/FIXES/NT40/ATAPI/ATAPI.EXE
    Execute ATAPI.EXE and copy the ATAPI.SYS file to a diskette.
2.During the installation, when asked for additional devices, add the large drive by
    specifying the new device from the ATAPI.SYS diskette.
3.During the NT install, format the hard drive with a NTFS partition of a minimum of 1
    GB and up to 7.8 GB.
4.Finish the NT installation.
5.When NT is fully installed:
    START > PROGRAMS > ADMINISTRATIVE TOOLS > DISK ADMINISTRATOR
6.Select the cross-hatched end of the hard drive > CREATE PARTITION and
ASSIGN DRIVE LETTER.
7.In Windows Explorer, format the new drive.

The CD is NT Service Pack 4 or higher.

1.During the NT install, format the hard drive with a NTFS partition of a minimum of 1 GB and up to 7.8 GB.
2.Finish the NT installation.
3.When NT is fully installed:
    START > PROGRAMS > ADMINISTRATIVE TOOLS > DISK ADMINISTRATOR
4.Select the cross-hatched end of the hard drive > CREATE PARTITION and ASSIGN DRIVE LETTER.
5.In Windows Explorer, format the new drive.

To dual boot with Windows 95/98.

The motherboard BIOS must support and recognize drives larger than 8 GB
before NT can access the entire drive.

Windows 95/98 and Windows NT can only share FAT16 partitions.

If you are installing Windows 98 first, make sure that the first parition is FAT16 [less than
2 GB]. NT will later be installed on the FAT16 partition. NT 3.5x and NT4 cannot access
FAT32 partitions, which is the default for Windows 98.

The CD is Service Pack 1.

1.Download Atapi.sys from Microsoft.
    FTP.MICROSOFT.COM/BUSSYS/WINNT/WINNT-UNSUP-ED/FIXES/NT40/ATAPI/ATAPI.EXE
    Execute ATAPI.EXE and copy the ATAPI.SYS file to a diskette.
2.During the installation, when asked for additional devices, add the large drive by specifying the new device from the ATAPI.SYS diskette.
3.During the NT install, install NT on the existing FAT16 partition and LEAVE THE FORMAT INTACT.
4.Finish the NT installation.
5.When NT is fully installed:
START > PROGRAMS > ADMINISTRATIVE TOOLS > DISK ADMINISTRATOR
6.Select the cross-hatched end of the hard drive > CREATE PARTITION and
ASSIGN DRIVE LETTER.
7.In Windows Explorer, format the new drive.

The CD is Service Pack 4.

1.Install NT on the existing FAT16 partition and LEAVE THE FORMAT INTACT.
2.Finish the NT installation.
3.When NT is fully installed:
START > PROGRAMS > ADMINISTRATIVE TOOLS > DISK ADMINISTRATOR
4.Select the cross-hatched end of the hard drive > CREATE PARTITION and
ASSIGN DRIVE LETTER.
5.In Windows Explorer, format the new drive.
How to change the spool directory?
