MEGASCSI partitioning?

Recently acquired a MEGASCSI with external HDD (via msx.org). Today I retrieved my SCSI ZIP drive from the shed (not used since 2005) and connected it. Seems still to work...

What is the best way to create and 'format' a FAT16 partition? I tried using sformat-2 but that keeps on going and never seems to end. Is there a FDISK like tool for MEGASCSI?

Hello,

Do you use the MEGA SCSI with a TurboR ? If yes is the Kernel.ROM installed ? (You can do this with MGinst.com)
MEGA SCSI works best with partitions. It is also possible to work with FAT 16, but have the experience that some programs do not work correctly.

With the program ESET.COM you can set the number of drives
Partitions: Use the command cp b: 1 cp c: 2 etc.

I think it is only possible on a PC to format a hard disk
SFORM-1.COM voor DOS 1
SFORM-2.COM voor DOS 2 (I think no difference)
MEGA SCSI works fine with a SCSI ZIP drive (100Mb) and SCSI CD ROM

Hi,
Thanks for your reply. I am not sure if Kernel.ROM is installed. How can I verify? The complete set (MEGASCI+external SCSI HDD) came from a Turbo-R user. The ramdisk (ASmile contains a set of megascsi utilities.

On the RAM disk there does not seem to be a kernel file.

Your Kernel.ROM is installed, because you have a Ramdisk (SRAM)drive as A:

Important : Copy all your files on A: to a new Disc,
because probably the battery in the MEGA SCSI is almost empty,
(When the battery is empty you lose all the files on your SRAM Drive)
The last time it was used you said was in 2005 !
If possible do not change the setup !

How many drives do you have ?

The content of the ramdisk is in the backup directory.

Thx guys, I had already found the backup of the RAM disk contents on the HDD. I am not sure if there is a kernel img in there. Do I need one to be able to restore the MEGASCSI?

I'll probably have to save the complete SRAM contents (including kernel??) with MGSAVE. Any maybe kernel with KSAVE?

BTW It is my ZIP drive that hasn't been used since 2005 Smile

Don't do this !

Clear !

For EXAMPLE you have a ZIP drive with a 100 Mb or 250 Mb disc :

If the Disc (100 Mb or 250 Mb) not formatted in Partitions (32 Mb parts) yet then you can use the follow :

- Connect only your ZIP drive (SCSI) to the MEGA SCSI for example
- Put your MSX on
- ESSET.COM
- E EASY SETUP
- C CONNECT DRIVE
- A:ESE-RAMDISK
- B: ID6 HD IOMEGA ZIP 100 or HD IOMEGA ZIP 250
- C: no connection ((ENTER & Cursor UP or DOWN ENTER)
- D: no connection ((ENTER & Cursor UP or DOWN ENTER)
- E: no connection ((ENTER & Cursor UP or DOWN ENTER)
- F: no connection ((ENTER & Cursor UP or DOWN ENTER)
- N DRIVES How many drives ? (0-8)
- Fill 2 in
- S SETUP Are you sure Yes
- Quit

When your in DOS your type CP16 B: (This is only one time)
In AUTOEXEC.BAT add FAT16
Reset you computer

If you don't have the programms FAT16.COM and CP16.COM i can mail this to you.

With respect to KSAVE/MGSAVE stuff, I'll leave that for another topic

There is no CP16 on the RAM disk. In autoexec.bat PARSET16 is used.

Back to my original question: how to create partitions for the MEGA-SCSI?
My conclusion from this thread: It seems there is no FDISK equivalent for MEGA SCSI other than S-FORM.
I do have a backup (plan) for creating partitions on a ZIP disk but a solution for MEGASCSI would be nice.
