HA55BS3 (Nippon Teksa) Non multi-vendor C bus bus master SCSI board. Although not compatible with Win95 (Nippon Texa has withdrawn from the PC-98 peripheral market before Win95 release), When using it, set the transfer mode to DMA transfer and let the 55 board driver recognize it. Reference http://web.archive.org/web/20010430164823/http://www.texa.co.jp:80/TEXA/ 　　　oshiete / answer / Windows.html ※ In TEXA, bus master transfer is expressed as synchronous transfer (synchronous mode), I / O transfer (CPU transfer, PIO transfer) may be described as GT mode. The transfer method is automatically selected by CPU and HDD discrimination. Synchronous mode is not available on V30 machines and PC-H98 series (it automatically becomes GT mode). In addition, synchronous mode is not possible even when the memory of 16 MB or more is installed in the PC body (Use in GT mode or DMA mode). Please use the following expansion slots for the following models: PC-9801VX0, 2, 4 ...... # 2, # 3, # 4 PC-98 XA ...... # 3, # 5 PC-286 V ...... # 2, # 3, # 4 PC-286LS (T), PC-386LS (C / X) / LSR ...... # 2 (left side seen from the back) Also, for the following models, when using the following expansion slots, set the DMA channel to 0 or 1 To be sure: PC-9801E ...... # 6 PC-9801F1, 2 / VF / VM0. 2, 4 ...... # 4 PC-9801F3 / U / UV / CV ...... # 2 PC-286U ...... # 2 Also, on the following models, attach the switch pin beside the card edge connector in reverse: PC-9801U / UV / CV / UR / UF * There is a case that the PC-9801UV2 does not operate due to the signal disturbance of the expansion slot. Also, in PC-9801DS, it may not operate normally, such as initialization can not be performed in synchronous mode.

This function is standard and can not be canceled ・ About "PL-Quick" (high-speed format) This mode simplifies HDD initialization and area allocation on MS-DOS. When formatting is done in this mode, initialization takes about 5 seconds and area reservation takes about 10 seconds. (※ As with the HA-55BS4, the “P-Quick function” is to simplify initialization. It seems to be "L-Quick function" to simplify area reservation) P-Quick enabled with kana key OFF and disabled with ON before launching format.exe. L-Quick enabled with CAPS key OFF, disabled with ON.When changing the sector length, When re-initializing an HDD that has been reset / power off while initializing / reserving an area, use PL-Quick. Cancel and initialize. About the startup screen: ID search screen is not displayed if Kana key is turned on at system startup (Because ID search itself is performed, system startup regardless of whether the search screen is displayed or not displayed Time does not change) -"Device =": Type of recognized SCSI device [Upper line] HD5: HDD with a sector length of 512 bytes / sector HD2: HDD with a sector length of 256 bytes / sector HD ......
