Virtual disk support (tcvd, tiny core virtual disk) is new in Tiny Core v1.4
This was primarily setup for Qemu support, but is useful for anyone.
It uses the Qemu virtual disk image ext2, a loopback file.
To use first specify the 'harddisk' file with the tcvd boot option followed
by your regular boot optons using tcvd, examples:
boot: tinycore waitusb=10 tcvd=harddisk tce=tcvd restore=tcvd
This will autoscan for the file named harddisk in level one directories and
setup mount capabilities as device tcvd. The subsequent tce=tcvd and restore=tcvd
will use the virtual drive special device.
boot: tinycore waitusb=10 tcvd=sda1/harddisk tce=tcvd restore=tcvd
This will look for the loopback file named harddisk on sda1 and setup a special
device tcvd used by the other boot opitons.
boot: tinycore waitusb=10 tcvd=sda1/qemu/harddisk tce=tcvd restore=tcvd
This is/was the typical Qemu setup that I used in Damn Small Linux.
Again a special device tcvd will be setup and then other boot options are able
to use it.
