Syslinux - Jan 2004 - Standard file extensions for zipped floppy images

Hi,

I was wondering what's the best standard file extension for zipped DOS 
disk images and ramdisks. I've been using the following standard:

	.zi			kernels, memtest86, memdisk
	.igz	.img.gz		zipped floppy images and ramdisks

I'd rather have a different extension for ramdisks, maybe

	.zim	zipped floppy images
	.zrd	zipped ramdisks

Any ideas ?


It would also be nice if syslinux would allow to look for kernels or 
ramdisks in a subdirectory. My project already has 20 kernels and 
ramdisks in the root-directory, and this will only increase in time.

Kind regards,

what kind of Syslinux device are you using then that holds all these images? a
harddisk?

since Syslinux uses DOS names, I tend to use .GZ
I don't know if Memdisk first looks for a Gzip header, or at file extension

gzip test.img
ren test.img.gz test.img

label test
kernel memdisk
append initrd=test.img

probably even test.bin is valid, as probably only Sys/PXE/ISOlinux themselves
look for reserved filename extensions.

is it possibly to specify a device, btw?
# reads diskette into Memdisk and then boots it.
label disk2ram
kernel memtest
append initrd=0x00 
 
I don't understand Memdisk decompression procedure, but do know that it
failed to decompress a filled 1.44MB image in a 4MB virtual machine in
Vmware..out of memory. Bochs did fine with just 4MB.

There is precedent (Winimage) for using .imz for zipped floppy images.
