It'll access the disk now but I don't know how to prep it. The pcd reverse video requires the 8741 to work so not yet.

I'll give it a shot later. I have prepared a disk image with a collection of all the different HDINIT versions.

For easy experimenting, I created three harddisk images each of the following types:

Rodime RO352 306-4-17-512
Micropolis M1303 830-5-17-512
Seagate ST251 820-6-17-512
BASF B6188 360-4-17-512
NEC D5126 615-4-17-512
NEC D5126 568-4-17-512 (as specified by the HDINIT 4.25U utility)
Mitsubishi MR522 612-4-17-512

@Tauwasser ... thanks for your research on the password, "siemens" was spot on

PC-D and PC-X stil have problems with the 512 Byte/Sector images ... the PC-D now recognizes the presence of a harddisk, but either goes through the motions marking each track invalid or complaining about a defective controller and/or harddisk. The PC-X goes through all tracks, marking them as defective and running out of spare tracks smile







P.S. The pics will be up soon, Dropbox is not syncing atm.

Try making them 18 sector tracks.

Thanks, mistake on my part ... I thought you had to change to 18 spt in the source to make it recognize 17 spt images.

Still no luck with the PC-D, but the PC-X now formats a 306-4-18-512 image nicely with Sinix 1.2 ... and even boots from the harddisk after the initial stage - with a 1024 byte/sector image it would hang afterwards.

I can't figure out how to use HDINIT. What does it expect on its command line?

Edit: It's "HDINIT RO352" for the Rodime. Anyway, it works now.

Yeah, from what I can gather from the HDINIT binaries, the 2.xx versions take no parameters, for the 4.25 versions you have to add one of the drive types it accepts as a parameter, just as you described.

Testing later, much excitement, very SCSI.

Guys, you still rock ;-)
Just in case, I've updated my PC-X page with some tips about gaining root permissions on an existing installation of SINIX and im/exporting data via 360KB DOSFloppy ('trados').

SCSI2SD, which is here, has been pretty active updating their firmware to support new hardware, most recently the E-mu EMAX sampler. The list of known working devices at the bottom of the page is pretty impressive - it even supports the super-oddball 1280 byte sectors (!) used by the Symbolics Lisp Machine.
