OPENMSX can actually boot MSX-DOS1 with C-BIOS v0.29?

I didn't know it was possible, but I managed to boot MSX-DOS1 with C-BIOS (v0.29) by using the Sunrise IDE extension. The following script replicates the process:

machine C-BIOS_MSX2
ext ide

set power off
diskmanipulator create hd.dsk -dos1 32M
hda hd.dsk
diskmanipulator format hda -dos1
diskmanipulator import hda dsk/
diskmanipulator dir hda
message "hd.dsk created"

The contents of dsk are: COMMAND.COM, MSXDOS.SYS and AUTOEXEC.BAT. Isn't it weird that MSX1 C-BIOS doesn't work, but MSX2/2+ BIOS do? Also: using C-BIOS font inside MSX-DOS is weird. Crazy

WebMSX can boot C-BIOS with normal Disk ROM (floppy), and also with the Nextor HDD support.
But, of course, depending on the software you will run, it may try to access BASIC or some unsupported BIOS routines and fail.

This is not a capability of an emulator, but of the C-BIOS and the emulated MSX machine configuration.

I thought C-BIOS was incompatible with disk adapters in general.

No, it isn't. It just doesn't implement a disk ROM itself.
