Re: ZIP on MSX
When partition tabels are different then you must always reboot! Also with Megascsi! 8-? You haven't never tested MegaSCSI, right? I can assure you that you DON'T need to reboot when you change the disk NEVER. DOS 2 work area is updated as well as MegaSCSI SRAM when a partition is changed, so everything works. Reset is needed only when you change the device assigned to a drive (at least this is advised by the device change program, actually I never tested it because I have only one device!). As a matter of fact the last thing I said I was indeed assuming you have to reboot. I haven´t tested it since I have all my zip-disks in the same format.

Re: ZIP on MSX
Nope! In MegaSCSI you can define the size of each partition (when formatting the device) with any amount of sectors. When you change the disk you don't need to do nothing if the new disk has the same partitionning layout as the previous; else, you must only to run the partition changer. What if you have one Zip-disk with 3 partitions and other with 4 partitions ? Everything is still working Ok ? Yes, the partition changer works no matter of the partitionning state of the disks. Howewer this program is not perfect yet, and sometimes goes wrong (and even hangs the computer) when you use non-ASPI disk. However the most normal (and logical) case is to act as you say: making all the partitions of the same size (32MB) except the last one. No exepts are needed if I'm correct. 3 * 32MB = 96MB that is actual size of formatted Zip-disk. Atleast my fdisk proggram says that all of the capasity is used, when I use 3 * 32MB format. The maximum amount of clusters handled by MSX-DOS is 4085, not 4096. Therefore the actual maximum size of the partitions is somewhat smaller than 32MB, and a little of disk space remains for a fourth partition. I define my partitions with 64000 sectors, so this extra partiton grows to about 2MB, enough for some little utilities. This is not necessary if you boot from the SRAMdisk (that is, if you assign it to drive A:). This is very useful, because you have the same booting state regardless of the inserted disk. Is it allways A-drive ? With Novaxis I have notised, that boot HD can be A-drive or C-drive depending of your slot configuration. I think, that C-drive is better because then I can boot from disk, and HD-boot is enabled only if disk was not present. (Just like in stupid PC) Anyway if I want to use this feature for example in MSX tR I need to add another disk controller before SCSI controller. (This is all tested information) Boot drive is always A:, but you can assign this drive to ESE-RAMdisk or to any device, or even leave it unconnected (but this is a little stupid!) 8-). Booting from diskette is never allowed in MegaSCSI, except if you boot pressing the appropriate key for disabling it. That's right. Maybe patching any hook on the disk work area this can be solved, because for check the disk change it is enough to read the serial number on the boot sector, and this is independent of the controller. It is not that easy... You have to update also all partition info from RAM and then starts battle against DOS. If someone has any glue about DOS2 internal variabbles, then please... DOS2 seems to keep same information usually in many places. ESE guys have this information and much more, else it is not possible to implement all the features of MegaSCSI (it has even a internal call for creating a new drive letter and assign it to a device!!) It's only that MegaSCSI designers took some time using the brain before the construction step. It is not so difficult. We can learn ( = COPY ) much from them. :-) Unluckily the only way is to DISSASSEMBLE their stuff, because now they are not easy to find via e-mail... because of this, my FAT16 project is frozen. --- Konami Man - AKA Nestor Soriano (^ ^)Y Itsumo MSX user [EMAIL PROTECTED] http://www.geocities.com/SiliconValley/Bay/9797/msx.htm This Pentium will become obsolete in 5 seconds... 4... 3... 2... --- MSX Mailinglist.

RE: ZIP on MSX
No partitions can be read by the other interface? [J.P. Zeedijk] Sometimes it seemes it sees the partition of MK disks on the novaxis (with fdisk utilities), but they are not accessable. The MK doesn't see anything on Novaxis disks. BTW: I think I have seen a utility to convert partition tabto gouda-novaxis and vice versa. I think this is the Bert interface. The Bert and MK should be almost the same! [J.P. Zeedijk] They seem to be the same. I could use harddisks from MK on Bert and vise-versa, I think ZIP disks would too. (a close vriend of mine has a BERT Interface. I used his setup utilities for my MK harddisk/zip and they work fine) Greetings Maico Arts MSX-NBN Greetings and till mail!

That one has jumpers for all SCSI ID's and termination. You are right about zip together with HD, because if you only use ZIP, you have to reboot when you want to change ZIP's. I have (in a 8250) a Seagate 20Mb on SCSI-ID 0, so booting and all major utillities are on that disk and all other stuff is on the ZIP's (I use 3 disks till now) I have on this MSX (8250 2+) Internal SCSI ZIP next to the HD. On the Turbo-R I have an IBM 200Mb harddisk as bootdisk and for extra capacity an external SCSI ZIP on ID 5. But a pitty is that the disks made on Turbo-R with Novaxis-Gouda are not exchangeable with the 8250's MK SCSI disks and vise-versa. I am still looking for a tool for this problem, because I want to transfer a lot of data (about 100Mb) to the Turbo-R. No partitions can be read by the other interface?
