; Disk driver to create FAT16/FAT32 memory-based temporary disk aka RAM disk.
; (c) CleverMouse
; Note: in the ideal world, a disk driver should not care about a file system
; on it. In the current world, however, there is no way to format a disk in
; FAT, so this part of file-system-specific operations is included in the
; driver.
; When this driver is loading, it registers itself in the system and does
; nothing more. When loaded, this driver controls pseudo-disk devices
; named /tmp#/, where # is a digit from 0 to 9. The driver does not create
; any device by itself, waiting for instructions from an application.
; The driver responds to the following IOCTLs from a control application:
SRV_GETVERSION equ 0 ; input ignored,
; output = dword API_VERSION
DEV_ADD_DISK equ 1 ; input = structure add_disk_struc,
; no output
DEV_DEL_DISK equ 2 ; input = structure del_disk_struc,
; no output
; For all IOCTLs the driver returns one of the following error codes:
NO_ERROR equ 0
ERROR_INVALID_IOCTL equ 1 ; unknown IOCTL code, wrong input/output size...
ERROR_INVALID_ID equ 2 ; .DiskId must be from 0 to 9
ERROR_SIZE_TOO_LARGE equ 3 ; .DiskSize is too large
ERROR_SIZE_TOO_SMALL equ 4 ; .DiskSize is too small
ERROR_NO_MEMORY equ 5 ; memory allocation failed
API_VERSION equ 1
; Input structures:
struc add_disk_struc
{
.DiskSize dd ? ; disk size in sectors, 1 sector = 512 bytes
; Note: .DiskSize is the full size, including FAT service data.
