Not sure but it must be, check it out and let me know as i haven`t burnt the image yet.
The dms flashes might be differant from the toxic ones WOWchamp,but you think that it should still work on the dms4 chip.Maybe there is a difference and using a dms flash on a toxic flash might not work but i`m not 100% sure on this.
If you have a hard drive plugged into the ps2 (ide) as i do on my v7 with a dms pro (not EZI) the machine will not reset when the hard drive is in operation, it will just shut off, i may be the only one with this scenario, but i doubt that it is the dms4 because my dms3+ had the exact same behavior with the same hard drive situation.
Nope i have magic modchip and when the hdd is running and i press reset button it puts the ps2 into stanby mode (red light) and you have to restart it again. It is designed this way to turn off so you don`t damage your hdd, as if you kept hitting reset before the hdd can actually get ready it would not be good for it. Hope info helps.
