New programs with sources by Luis Claudio Grosso: CHANGE and PUTBOOT and RAMDISK

CHANGE and PUTBOOT

Disassembled CHANGE a SVI-738 utility that changes the boot sector of diskettes to allow space for the 80 column driver. 'Change' replaces the whole boot sector, included the parameters area, this works fine with single sided diskettes, but... 'changing' a double side diskette, makes the directory no longer available. To solve this problem PUTBOOT is written. This utility writes the whole boot sector (with the /F option) or the executable part only from a 512 byte file. The syntax is:
PUTBOOT [D:]SOURCEFILE DESTDRIVE: [/F]
Where:
- SOURCEFILE is the 512 byte source file
- DESTDRIVE is the destination drive where the boot will be written
- /F if present, the whole boot sector is written, otherwise only the executable part is written.

Also included is the disassembly of a standard DSDD boot sector 738DBOOT.ASM inside PUTBOOT and the disassembly of a 'changed' SSDD boot sector 738SCHGD.ASM inside CHANGE.ZIP.

RAMDISK

Luis bought a Padial's LPS-4MB-V3 for his SVI-738, a 4mb memory expansion for MSX. The RAMDISK is a disassembled and slightly enhanced RAMDISK suitable for such a large amount of memory. In the archive both the original buggy version and the bugfixed version of RAMDISK.
