04b9735975 Quick timer fix on the T128/PAS SCSI (May 10th, 2025) 
1. If the timer result is less than 10.0 microseconds, then adjust it to 10.0. Fixes some timing read issues with the T128 (and possibly PAS SCSI).
2. Remove unused variables.

e800f99f5a Make device.c assume CONFIG_BIOS is first in the config struct and make sure any device_t struct containing such follows that, in order to not have to traverse the entirety of every single device_t's config struct in the Settings dialog - should reduce the dialog's loading times further. 2025-05-10 04:53:20 +02:00

ebf125082a Revert a minor commit from Spock. (April 7th, 2025) 
This fixes OS/2 Warp on a PS/2 machine using the Spock/Tribble during the file copy phase (the bug was probably too many IRQ's being fired).

9c8c1a6f40 Trantor SCSI changes of the day (April 2nd, 2025) 
1. The PAS SCSI controller driver mamv1.sys dislikes having bits 0-6 set when a transfer has completed, take account from this, fixes mamv1.sys incomplete CD transfers (bits 0-6 get re-enabled when the transfer is ongoing).
2. I now understand why the T128 doesn't have a block count register, it does the block count manually from the SCSI layer directly, this fixes Pseudo-DMA transfers when using, e.g.: CD transfers using a sector size of 2340 bytes.

6d43f7e2df More fixes for 5380-based SCSI chips of the day (March 29th, 2025) 
1. Avoid audio stops when they don't need to be.
2. And improved the MMIO-based NCR 53c400 timings to be similar to the port I/O-based one (T130B).
3. Minor timing fixes to the T128/PAS as well (especially for the hdd, when entering Windows 1.x using a SCSI HDD).

a2534c1f4f Trantor T128/MediaVision SCSI changes of the day (March 8th, 2025) 
1. Made as best as possible implementation of the status bits 1-2 of the Trantor 128 so to make a more accurate speed for SCSI devices (CD-ROM and HDD) without stalls.
2. Slightly reorganized the timer of the T128.

1. Make IRQ's more correct and per manual.
2. Only an adapter reset command should reset the SCSI devices connected to it.
3. Differentiate the two controllers by the connector bit (pos3 bit 12) in the CMD GET POS INFO SCB command.
4. Actually emulate bit 7 of pos4 in the pos writes so that selection between 16KB and 32KB rom loading is done properly.
5. Some cleanups.
